The patient improved after antiviral treatment but eventually developed severe respiratory distress syndrome and cardiac insufficiency. His respiratory secretions were tested for nucleic acids and turn negative twice. Computed tomography image of the patient showed evidence of viral pneumonia on the 11(th) day of onset and continued to worsen. The patient was finally intubated and transferred to a higher-level care center for further treatment. We were very focused on infectious disease protection throughout the treatment, however, suboptimal treatment was provided due to the switch in antihypertensive medication, lack of early nutritional support, and fluid restriction management.

Pneumonia, Viral; Hypertension; Enteral Feeding; •The later the onset of symptoms in COVID-19 patients, the higher the possibility of progression to severe disease. •Airway care should prevent aerosol transmission of viruses. •Changes in antihypertensive medications in the setting of COVID-19 should be completed only after carefully assessment. •The progression of COVID-19 is rapid, and early enteral nutritional support has positive effects on the improvement of ARDS and mechanical ventilation. •Pulmonary circulation congestion caused by COVID-19 may increase the risk of heart failure in patients with heart disease, and fluid restriction management is important. Coronavirus disease 2019 (COVID-19) is a respiratory infection disease that impairs the lungs caused by sever acute respiratory syndrome coronavirus 2 (SARS-CoV-2), now is outbreaking worldwide (Zhang JJ et al., 2020) . As the disease is highly contagious and comes with a considerable morbidity and mortality, policy makers and healthcare workers are facing challenges in terms of population-based preparedness, infection prevention & control, disease management, and end-of-life care (Garcia-Alamino JM 2020; Jansson et al.,2020; Lucchini et al., 2020; Pattison 2020) . COVID-19 pneumonia manifests with chest CT imaging abnormalities peripheral distribution (Shi et al.,2020) , probably because the virus can not tolerate the air flow from the central bronchus similar to other infectious pneumonia to invade the bronchioles, resulting in pulmonary circulation disorder and acute respiratory distress syndrome (ARDS). Most people infected with COVID-19 have mild disease and recover, and individuals at highest risk for severe disease include people aged over 60 years or those with multiple comorbidities (WHO-China joint mission, 2020). In this study, we present the case of a young COVID-19 patient with the history of hypertension. Antiviral therapy was initiated. His respiratory secretions were tested for nucleic acid and turned negative twice but worsened progressively thereafter. In addition to the mechanism of disease, the necessity of prompt nursing interventions might not be neglected during patient care. A 41-year-old male was admitted to an isolation ward in the infectious disease specialist hospital, Guangzhou, China, with a 3-day history of intermittent dry cough and low-grade fever accompanied by chills, and his oropharyngeal swabs test was positive for SARS-CoV-2 and verbally confirmed to the patient. He disclosed a visit to Wuhan 14 days ago and contacted with a health care provider 3 days ago because of the symptoms and recent travel. Three years to presentation, he was diagnosed with hypertension and managed with irbesartan. The patient had a body temperature of 37.5℃，blood pressure of 143/100 mmHg, pulse of 106 beats/minute, respiratory rate of 20 breaths/minute, and oxygen saturation of 98%. The laboratory examination revealed an increase of D-dimer and some myocardial enzymes (Table 1) . Computed Tomography (CT) scan showed no abnormalities. The patient received kaletra, oseltamivir and moxifloxacin treatment, and supplemental oxygen by nasal cannula at 2 L/minute. On days 2-7 of hospitalization, apart from the intermittent low-grade fever, the patient no longer reported cough and chills. The patient reported dizziness on day 5 and started to take irbesartan orally. On day 7, the patient reported abdominal discomfort and passed loose stool. Given the gastrointestinal side effects of kaletra, bifid triple viable capsules were added for regulating gastrointestinal tract. On day 8 of hospitalisation, the patient reported fever (38.6 ℃ ) and chest tightness. Although the real-time reverse transcription-polymerase chain reaction (rRT-PCR) was negative on day 8, the second CT scan showed ground-glass opacification in both lungs. Laboratory results from day 8-14 are shown in Table 1 . The second rRT-PCR on day 10 was positive, and the third CT scan on day 12 showed higher opacification range than before. The treatment included antipyretic therapy, teicoplanin, and 3-day course of methylprednisolone; the calcium antagonist levamlodipine was given instead of the angiotensin receptor blocker irbesartan because the angiotensin converting enzyme 2 (ACE2) has been shown to be a co-receptor for viral entry for SARS-CoV-2 (Zhou et al., 2020) . The patient had diarrhea for 2 days (9 th and 13 th days). As he had ongoing fevers, eight respiratory pathogens were tested and blood cultures were obtained, but the results were negative. On day 14, negative SARS-CoV-2 RNA reappeared. On day 15, the patient's body temperature was 40 ℃ with mild cough, expectoration, chills, and muscle soreness. For symptom management, oxygen level was increased at 3 L/minute. On day 16, the patient was lethargic and reported palpitation of sudden onset, paroxysmal cough accompanied with sputum, and loss of appetite. His body temperature was 39.7 ℃ ， pulse 130 beats/minute, the respiratory rate 31 breaths/minute, and the oxygen saturation 99% while breathing oxygen at 6 L/minute. The fourth CT performed showed significant exacerbation of viral pneumonia (Figure 1 ), and the rRT-PCR turned positive for the second time. The patient was notified of severity and admitted to the intensive care unit (ICU). In the ICU, sulperazone were administered intravenously, ambroxol and acetylcysteine were used as expectorants by aerosol inhalation. The next afternoon, the patient had cyanosis and coughed with bloody sputum. The respiratory rate was 36 breaths/minute and oxygen saturation was95% with high-flow oxygen. The patient was started on noninvasive positive pressure ventilation [positive end-expiratory pressure (PEEP) was setting 5 cm H 2 O; fraction of inspiration (FiO 2 ) was 70%] under morphine sedation. The chief physician changed medication from sulperazone to meropenem. The laboratory results (after 1 hour) showed ongoing leukocytosis, lymphopenia, and an increase in neutrophils, liver enzyme, myocardial enzyme, and decrease in oxygen partial pressure for the first time (Table 1) . At this point, the ratio of the partial pressure of arterial oxygen (PaO 2 ) to FiO 2 (PaO 2 :FiO 2 ) ＜ 100mmHg indicated that severe ARDS had occurred (World health organization, 2020). Chest radiograph showed enlargement of cardiac shadow ( Figure 2 ). As the condition deteriorated, the patient underwent endotracheal intubation via electronic bronchoscope adaptive pressure mode (parameters: respiratory frequency of 20 times per minute; tidal volume of 420 ml; PEEP of 10 cmH 2 O; FiO 2 of 85%). After intubation, the patient's ventilation pattern was smooth, with no obvious patient-ventilator dyssynchrony. The next day, the patient's vital signs were stable under ventilator-assisted breathing. Given the enhanced inflammatory response, progressive severe ARDS, and the possibility of cardiac insufficiency, the patient was transferred to another high-level ICU for further treatment. After 13 days of follow-up, the patient was weaned from mechanical ventilation. After 17 days of follow-up, the patient tested negative for SARS-CoV-2did not become positive since then. In this patient, the clinical symptoms aggravated only on the eleventh day, and CT showed novel coronary pneumonia. A recent study found that a majority of patients with COVID-19 are hospitalized after a period of improvement and then deteriorated . Several studies reported that patients with negative nucleic acid tests after treatment became positive later (Zhang Q et al., 2020) , this is consistent with this patient who turned positive after two negative nucleic acid tests. Possibly as the body's immunity is low, the virus has not been removed, and the cells are still in a toxin state, but the amount of detoxification in the body has not yet reached the amount of virus required for a positive nucleic acid test. Therefore, combined with the clinical symptoms, radiography can estimate disease progression more accurately than nucleic acid detection only. In this case, the patient wore a surgical mask while inhaling oxygen, and the nurse attached the tube with a sling to avoid displacement of the nasal cannula. As high-flow oxygen therapy could not improve patient's symptoms, he received non-invasive ventilation in a closed loop with virus filtering function. Finally, the anesthesiologist intubated the patient with the rapid induction of anesthesia using sedatives combined with muscle relaxants to eliminate the patient's cough. These were measures to reduce the spread of the virus through aerosols. However, expectorant treatment was done by atomization, and for patients with COVID-19 without chronic obstructive pulmonary disease or asthma, unnecessary atomization should be avoided (Respiratory care committee of Chinese thoracic society, 2020). The patient had diarrhea, electrolyte imbalance, and loss of appetite; however, enteral feeding was not initiated before or after mechanical ventilation. Nutritional support is recognized as a major support during critical illness (Rice et al., 2012) .The incidence of malnutrition in ARDS patients is very high due to severe stress, hypercatabolism, and significantly enhanced work of respiratory muscles. Energy demand might increase by 30% to 50%, and the incidence of malnutrition can be as high as 70% (Wheeler and Bernard,2007) . Numerous studies indicated that early enteral feeding initiated within 12-24 hours resulted in a significant lowering of the level of proinflammatory cytokines, stabilizing glycaemia, earlier restoration of gastrointestinal function, improving pulmonary oxygenation, and reducing the length of mechanical ventilation (Hurt et al.,2012) . Total parenteral nutrition is to be avoided when possible, in order to reduce the risk of complications associated with the use of central venous catheters. (Conoscenti and Blot, 2020; Huang et al., 2020; Khoshbaten et al.,2013) . However, Due to the patient's hypertension, and to avoid nosocomial crossinfection, cardiac function was not evaluated by doppler ultrasound, and diuretics were not considered to limit fluid overload. Pulmonary circulation congestion caused by COVID-19 pneumonia and the use of meropenem for the prevention of ventilator-associated pneumonia may increase the risk of cardiac insufficiency (Qin et al., 2020) . ICU nurses should carefully monitor the rate of intravenous infusion, but no reliable fluid balance was reported. While the latter is standard practice, the failure of complying with this recommendation can be interpreted in the light of the high workload during the In terms of medication management, there is concern that the use of angiotensin receptor blockers will increase expression of ACE2 and increase patient susceptibility to viral host cell entry and propagation. But the switch of antihypertensive medication may lead to the chaos of ACE2 receptor pathway, resulting in the imbalance of renin-angiotensin system and the aggravation of pulmonary inflammation (Patel and Verma, 2020) . Antihypertensive medication changes between classes additionally require frequent dose adjustment and management of adverse effects and increases the risk of medical errors. The council on hypertension of the European society of cardiology recommended continuation of treatment with usual antihypertensive therapy because there is no clinical or scientific evidence to suggest that treatment with angiotensin receptor blockers should be discontinued in case of COVID-19 (European Society of Cardiology, 2020). In addition to a part of the epidemic prevention and control factors affected by lack of testing, the blood test for inflammatory mediators was not perfect. No causal relationships can be drawn from this case study because alternative explanations for worsening symptoms cannot be ruled out. The present case study is illustrative for the need for clinical guidelines optimizing the processes of care. This is a case with delayed symptoms who eventually developed severe ARDS. CT images and hemolytic lymphocyte counts are more valuable than rRT-PCR results for the progression of COVID-19. For patients with hypertension, the replacement of antihypertensive drugs should be more carefully considered. Failure to administer nutritional support and fluid restriction can weaken the immune system and increase the risk of cardiac insufficiency. For this kind of respiratory tract infectious disease, unnecessary examination should be avoided as far as possible. Multiple ground-glass opacification in both lungs, more than 75% of the lungs were involved. The shadow of the heart was enlarged and full.
