Correct Answer: A

Rationale: The correct answer is to 'Use a soft toothbrush.' A soft toothbrush is recommended because it is less likely to cause the gums to bleed in clients with leukemia, who are at risk of bleeding due to overcrowding of white cells at the expense of other cell types like platelets. Choice B, 'Use dental floss daily,' is incorrect because dental floss is contraindicated and can make the gums bleed in clients with leukemia. Choice C, 'Hold pressure on any scrapes for 1-2 minutes,' is incorrect because when clotting is impaired, pressure should be held for 5-10 minutes or longer until the bleeding stops. Choice D, 'Use a triple-edged razor,' is incorrect because an electric razor should be used instead of a triple-edged razor to prevent small cuts and bleeding in clients with leukemia.

Correct Answer: B

Rationale: The correct answer is B because pain in the left calf could indicate a potential neurovascular complication related to the casted extremity. It could suggest issues such as compartment syndrome or impaired circulation. Option A is not as concerning since not elevating the extremity may lead to swelling but is not an immediate concern. Option C indicates itching, which is common with casts and not as concerning as potential neurovascular issues. Option D, regarding arthritis in the wrists, is unrelated to the lower extremity issue being screened for.

Correct Answer: C

Rationale: In this scenario, the most appropriate medication to relieve severe ischemic chest pain during a stress test is Procardia. Procardia, a calcium channel blocker, is effective in quickly alleviating chest pain by dilating coronary arteries, improving blood flow to the heart muscle. Aspirin, although important for antiplatelet effects, is not the best choice for immediate relief of severe chest pain. Diazoxide is a vasodilator used in hypertensive emergencies, not for acute chest pain. Mannitol is an osmotic diuretic used to reduce intracranial pressure, not for chest pain relief.

Correct Answer: D

Rationale: The correct answer is D, 'Illness lasting more than 6 months.' Chronic conditions lasting more than 6 months are not considered a contraindication for immunization. Choice A, 'Seizures,' can be a contraindication in certain situations, especially if linked to a specific vaccine component. Choice B, 'Fever lasting more than 3 days,' can be a temporary precaution but not a general contraindication. Choice C, 'Malignancy within the past 3 months,' is a contraindication due to the compromised immune system in cancer patients.

Correct Answer: B

Rationale: The correct answer is to consider the possibility of self-harm during the assessment process. This is crucial because unless the client is first assessed for self-harm or suicide potential, the necessary degree of vigilance in the client's environment may not be observed. While understanding the meaning of current stressors is important for treatment planning, ensuring the client's safety takes precedence. Motivation to participate in treatment and the presence of alcohol or other drug use are also important aspects to assess but ensuring the client's safety is the top priority in this scenario.
