Correct Answer: C

Rationale: The most appropriate nursing diagnosis for this client is C: Deficient fluid volume related to osmotic diuresis induced by hypernatremia. The client's elevated sodium level of 152mEq/L indicates hypernatremia, which leads to osmotic diuresis and subsequent fluid loss. This results in deficient fluid volume, causing the client to urinate frequently and experience fatigue from lack of sleep. The other choices are incorrect because: A: Deficient fluid volume related to inability to conserve water is not the most appropriate diagnosis as the primary issue is the osmotic diuresis induced by hypernatremia, not the client's inability to conserve water. B: Imbalanced nutrition: Less than body requirements related to hypermetabolic state is not the most appropriate diagnosis as the client's weight loss is likely due to fluid loss from osmotic diuresis, not a hypermetabolic state. D: Imbalanced nutrition: Less than body requirements related to catab

Correct Answer: C

Rationale: The correct answer is C because a lack of response to intradermal anergy testing suggests an inability to mount a normal delayed-type hypersensitivity response, indicating immunodeficiency. This could be due to conditions such as HIV, which impairs cell-mediated immunity. Choice A is incorrect because absence of reaction does not necessarily indicate lack of previous exposure to antigens. Choice B is incorrect as the absence of response doesn't confirm the presence of antibodies. Choice D is incorrect because anergy testing is not used to assess allergy, but rather to evaluate cell-mediated immunity.

Correct Answer: D

Rationale: The correct answer is D: Wheezing. Anaphylaxis is a severe allergic reaction that can lead to airway constriction and difficulty breathing, resulting in wheezing. Wheezing is a common symptom of anaphylaxis due to bronchospasm and airway swelling. Dermatitis (A) is a skin reaction, sinusitis (B) is inflammation of the sinuses, and delirium (C) is a state of mental confusion, which are not typical symptoms of anaphylaxis. Wheezing is a critical symptom in anaphylaxis as it indicates potential airway compromise and the need for immediate medical intervention.

Correct Answer: B

Rationale: The correct answer is B: Stage 2 hypertension. The patient's BP readings consistently fall within the range of 160-179 systolic or 100-109 diastolic, which aligns with the criteria for Stage 2 hypertension based on the current guidelines. This classification indicates a higher level of hypertension that requires prompt medical attention and intervention to reduce the risk of complications. Choices A, C, and D are incorrect because they do not correspond to the BP readings provided, falling outside the range for prehypertension, Stage 1 hypertension, and posthypertension.

Correct Answer: C

Rationale: The correct answer is C: Weak, slow pulse. Circulatory overload typically presents with signs of fluid volume excess, such as moist gurgling respirations, distended neck veins, dyspnea, and coughing. A weak, slow pulse is not a characteristic sign of circulatory overload, as the heart rate may actually be elevated due to the increased fluid volume. Therefore, a weak, slow pulse would not be likely to occur in this scenario.
