Nutrition HESI Practice Exam

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: The correct answer is B because a positive acid-fast bacillus smear in an elderly factory worker suggests tuberculosis, a serious communicable disease that must be reported promptly to the public health department to prevent its spread. Choice A is incorrect as Shigella is an important pathogen, but it does not require immediate public health reporting. Choice C is incorrect because Pneumocystis carinii is an opportunistic pathogen and does not require urgent public health reporting. Choice D is incorrect as varicella-zoster virus causes chickenpox and shingles, both of which are not reportable diseases to the public health department.

Correct Answer: C

Rationale: In a client with COPD, it is crucial to prevent carbon dioxide retention by avoiding high oxygen levels. As the client's oxygen is running at 6 liters per minute and he is showing signs of oxygen toxicity, such as flushed color and low respirations, the nurse's priority should be to lower the oxygen rate. This action helps prevent worsening the client's condition. Obtaining an EKG, placing the client in high Fowler's position, or taking baseline vital signs are important assessments but addressing the potential oxygen toxicity takes precedence in this scenario.

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: C

Rationale: The correct answer is C, Peanut butter. While kidney beans, strawberries, and whole wheat bread are high-fiber foods that help alleviate constipation, peanut butter is not a significant source of fiber. Peanut butter is more known for its protein and healthy fats content rather than being a good source of dietary fiber. Therefore, it should not be included as a primary recommendation for a high-fiber diet in the context of addressing constipation.
