HESI Nutrition Exam

Correct Answer: C

Rationale: The correct answer is C: Chloride. Chloride levels are typically low in cases of hyponatremia, as it often accompanies sodium loss. Magnesium (choice A) is not directly related to hyponatremia. Calcium (choice B) and Potassium (choice D) levels are usually not significantly affected by hyponatremia, making them less likely to be below the expected reference range in this scenario.

Correct Answer: B

Rationale: Dry mucous membranes are a classic sign of dehydration, especially in elderly individuals. Dehydration can lead to decreased moisture in the mucous membranes, making them dry. Skin turgor, although commonly assessed for dehydration in younger individuals, may be less reliable in the elderly due to changes in skin elasticity. Elevated temperature is more indicative of an infection or other conditions. Increased pulse pressure is not typically associated with dehydration in the elderly.

Correct Answer: D

Rationale: Assessing pupil responses is crucial in a client with hypertensive crisis to monitor for signs of increased intracranial pressure, which can indicate potential neurological complications. While heart rate, pedal pulses, and lung sounds are important assessments, they do not take precedence over neurological assessments in this critical situation.

Correct Answer: A

Rationale: The correct answer is A because monitoring for orthostatic hypotension is crucial when clients are receiving antipsychotic drugs since it is a common side effect. Orthostatic hypotension can lead to symptoms like dizziness and falls, making it essential to monitor blood pressure regularly. Choices B, C, and D are incorrect because most antipsychotic drugs do not typically cause elevated blood pressure, monitoring blood pressure is not directly related to the amount of sodium in the diet, and blood pressure monitoring is not primarily used to determine the need for anti-parkinsonian drugs in clients receiving antipsychotic medications.

Correct Answer: C

Rationale: When a client is receiving intravenous antibiotics, checking the IV site for signs of phlebitis is a priority assessment for the nurse. Phlebitis is an inflammation of the vein, which can lead to serious complications such as infection and thrombosis. Monitoring the IV site helps prevent these complications and ensures the safe delivery of antibiotics. While monitoring the client's temperature, pain level, and respiratory status are important assessments, they are not the priority in this scenario where IV antibiotic administration requires close monitoring for complications like phlebitis.
