A nurse is caring for a client who is receiving morphine for pain management. Which of the following findings indicates the client is experiencing an adverse effect of the medication?

Correct Answer: C

Rationale: Urinary retention is an adverse effect of morphine, as it can lead to the relaxation of the detrusor muscle and sphincter constriction in the bladder. Diaphoresis, hypotension, and tachycardia are common side effects of morphine due to its vasodilatory effects and impact on the autonomic nervous system. Diaphoresis is excessive sweating, which can be a normal response to pain or fever. Hypotension and tachycardia can occur due to morphine's vasodilatory effects and its impact on the cardiovascular system. Therefore, the presence of urinary retention would indicate the need for further assessment and intervention.

Correct Answer: B

Rationale: The correct answer is to avoid exposing the irradiated area to direct sunlight. Direct sunlight can further damage the skin during radiation therapy. Choice A is incorrect because alcohol-based lotions can irritate the skin further. Choice C is incorrect because mild soap and water can be drying to the skin. Choice D is incorrect because applying ice packs can cause additional skin damage during radiation therapy.

Correct Answer: D

Rationale: The correct answer is D, decreased platelet count. In disseminated intravascular coagulation (DIC), there is widespread activation of clotting factors leading to the formation of multiple blood clots throughout the body, which can deplete platelets. A decreased platelet count is a hallmark of DIC. Elevated hemoglobin (choice A) and elevated white blood cell count (choice B) are not specific indicators of DIC. While fibrinogen levels (choice C) can be decreased in DIC due to consumption, a decreased platelet count is a more specific and early sign of DIC development.

Correct Answer: B

Rationale: Correct Answer: The healthcare professional should review serum creatinine levels before administering metformin to assess kidney function. Metformin is excreted by the kidneys, and checking serum creatinine helps prevent lactic acidosis, a potential side effect in individuals with impaired renal function. Choice A: Potassium levels are not directly related to the administration of metformin. While monitoring potassium levels is important for some medications, it is not the priority when initiating metformin. Choice C: Sodium levels are not typically assessed specifically before starting metformin. It is not a routine lab test required prior to metformin administration. Choice D: Hemoglobin A1C reflects long-term blood sugar control and is not a lab test that needs to be reviewed before initiating metformin. It is used to monitor diabetes management over time, not for immediate medication administration considerations.

Correct Answer: B

Rationale: The correct answer is to check gastric residual volumes every 4 hours. This action helps prevent aspiration by ensuring the stomach is emptying properly, reducing the risk of reflux and aspiration. Elevating the head of the bed to 30 degrees can help prevent aspiration by promoting proper digestion and reducing the risk of regurgitation. Administering the feeding at room temperature is important for patient comfort but does not directly prevent aspiration. Flushing the feeding tube with water every 8 hours is important for tube patency but does not directly prevent aspiration.
