Nutrition HESI Practice Exam

Correct Answer: B

Rationale: The correct answer is to assist the client to turn, deep breathe, and cough. This intervention helps to expand the lungs and prevent atelectasis in postoperative clients. Maintaining adequate hydration is important for overall health but is not the most effective intervention for preventing atelectasis. Ambulating the client within 12 hours is beneficial for preventing complications after surgery, but it may not be as directly effective in preventing atelectasis as turning, deep breathing, and coughing. Splinting the incision is important for postoperative care, but it does not specifically address the prevention of atelectasis.

Correct Answer: D

Rationale: A serum potassium level of 6 mEq/L indicates hyperkalemia, which can be life-threatening and requires immediate intervention. Hyperkalemia can lead to dangerous cardiac arrhythmias and must be addressed promptly. The other options are not as urgent. A blood urea nitrogen level of 50 mg/dl may indicate kidney dysfunction but does not require immediate intervention. Hemoglobin of 10.3 g/dl may suggest anemia, which needs management but is not an immediate threat. A venous blood pH of 7.30 may indicate acidosis, which is concerning but not as acutely dangerous as hyperkalemia.

Correct Answer: B

Rationale: Chronic alcohol use disorder can lead to vitamin B6 deficiency due to impaired absorption and increased excretion of the vitamin. While clients with cystic fibrosis may be at risk for fat-soluble vitamin deficiencies, such as vitamins A, D, E, and K, they are not specifically at high risk for vitamin B6 deficiency. Clients taking phenytoin are at risk for folate deficiency, not vitamin B6. Clients prescribed rifampin for tuberculosis are at risk for vitamin D deficiency, not vitamin B6.

Correct Answer: B

Rationale: In cases of preeclampsia with increasing blood pressure, the priority action for the nurse is to have the client turn to the left side. This position helps improve blood flow to the placenta and fetus, reducing the risk of complications. Checking the protein level in urine (Choice A) is important for assessing preeclampsia but not the immediate priority when blood pressure is increasing. Taking the temperature (Choice C) is not directly related to addressing increased blood pressure in preeclampsia. Monitoring urine output (Choice D) is essential but not the first action to take when blood pressure is rising.

Correct Answer: B

Rationale: Assessing for signs of infection at the insertion site is the priority when caring for a client with a chest tube. Infection at the insertion site can lead to serious complications such as empyema or sepsis. Monitoring respiratory status is essential but assessing for infection takes precedence to prevent immediate harm. Assessing for subcutaneous emphysema is important but not the priority unless it compromises respiratory function. Checking the chest tube for kinks or occlusions is crucial for proper drainage but is not the priority when infection is a concern.
