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: D

Rationale: The correct answer is D, International normalized ratio (INR). INR is used to monitor the therapeutic effect of warfarin, an anticoagulant medication. Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors. Monitoring the INR helps assess how well the medication is working to prevent blood clots. Choices A, B, and C are not specific indicators for monitoring the effectiveness of warfarin. Hemoglobin levels primarily assess the oxygen-carrying capacity of red blood cells, platelet count evaluates the clotting ability of blood, and PT measures the time it takes for blood to clot. While these values are important for overall health assessment, they do not directly reflect the anticoagulant effects of warfarin.

Correct Answer: B

Rationale: Clients receiving chemotherapy are instructed to avoid fresh fruits and vegetables to lower the risk of infection. Fresh produce may harbor bacteria or other pathogens that could be harmful to individuals with compromised immune systems. Taking the temperature daily may be important but is not directly related to preventing infection. Limiting high-protein foods is not necessary unless there are specific dietary restrictions due to the treatment plan. Increasing the intake of high-fat foods is not recommended during chemotherapy as a high-fat diet may lead to other health issues.

Correct Answer: D

Rationale: The correct answer is D. After cataract surgery, wearing an eye shield at night for 2 weeks is essential to protect the eye during the initial healing period. Choice A is incorrect because significant eye pain should not be expected for the first 2 days after surgery. Choice B is incorrect as bending at the waist can increase intraocular pressure, which should be avoided postoperatively. Choice C is incorrect as there is no need to avoid sleeping on the side of the body that was operated on after cataract surgery.

Correct Answer: C

Rationale: In this scenario, the FHR baseline of 100/min for the past 15 minutes indicates fetal bradycardia, which can be caused by maternal hypoglycemia. Maternal hypoglycemia can lead to decreased oxygen supply to the fetus, resulting in fetal bradycardia. Maternal fever (Choice A) typically presents with tachycardia in the fetus rather than bradycardia. Fetal anemia (Choice B) is more likely to manifest as tachycardia due to compensation for decreased oxygen delivery. Chorioamnionitis (Choice D) may lead to fetal tachycardia as a sign of fetal distress, not bradycardia.
