Correct Answer: D

Rationale: The correct answer is D: Hyperosmolar solutions used primarily to reverse negative nitrogen balance. Rationale: 1. Hyperalimentation solutions are designed to provide essential nutrients intravenously. 2. Hyperosmolar solutions have a higher osmolarity compared to body fluids, providing concentrated nutrition. 3. Negative nitrogen balance occurs when the body breaks down more protein than it synthesizes, requiring additional protein intake. 4. Hyperosmolar solutions can provide adequate protein and nutrients to reverse negative nitrogen balance. Summary: A: Hypotonic solutions do not increase osmotic pressure, but rather decrease it. B: Hypertonic solutions are not primarily used for hydration in this context. C: Alkalizing solutions are not the primary purpose of hyperalimentation and do not directly address cellular sweating.

Correct Answer: C

Rationale: The correct answer is C: "It is a temporary interruption in the blood flow to the brain." This response is correct because it accurately describes a transient ischemic attack (TIA) as a temporary condition where blood flow to the brain is briefly interrupted. This explanation is clear, concise, and provides the family member with an accurate understanding of TIA. Choice A is incorrect because it deflects the question and suggests involving the doctor unnecessarily. Choice B is incorrect as it inaccurately states that TIA causes permanent brain damage, which is not true. Choice D is incorrect as it simply defines the acronym without providing any meaningful information about what TIA actually is.

Correct Answer: B

Rationale: The correct answer is B: Reduced sneezing. Decongestants work by constricting blood vessels in the nasal passages, reducing swelling and congestion, which in turn can lead to a decrease in sneezing. Increased salivation (choice A) is not a typical effect of decongestants. Increased tearing (choice C) is more commonly associated with allergies or irritants. Headache (choice D) can be a side effect of decongestants due to their impact on blood vessels, but it does not necessarily indicate effectiveness in treating allergic rhinitis.

Correct Answer: A

Rationale: The correct answer is A: Measure the client’s oral temperature. This is the best follow-up because it directly assesses the client's body temperature, providing objective data to confirm the presence of fever. It is essential to gather accurate information to guide appropriate interventions. Asking a colleague for assistance (B) may not address the immediate need for temperature assessment. Giving the client a clean gown and warm blankets (C) may provide comfort but does not address the need for temperature measurement. Obtaining an order for blood cultures (D) is not the initial priority when the client is showing signs of fever; temperature measurement is the first step in assessing the client's condition.

Correct Answer: C

Rationale: Step 1: Hyponatremia is an electrolyte imbalance characterized by low sodium levels in the blood. Step 2: Restricting fluid intake helps prevent further dilution of sodium in the blood, aiding in correcting hyponatremia. Step 3: Administering sodium can lead to rapid correction, risking osmotic demyelination syndrome. Step 4: Choice C is correct as it aligns with the goal of managing hyponatremia by preventing fluid overload symptoms. Summary: A, B, and D are incorrect as they do not directly address the primary concern of correcting low sodium levels in hyponatremia.
