Correct Answer: D

Rationale: A water-soluble lubricant is safe to use in conjunction with oxygen therapy, unlike petroleum jelly which is flammable.

Correct Answer: B

Rationale: The correct answer is B: 'Report increased bruising or bleeding.' Enalapril, an ACE inhibitor, can lead to thrombocytopenia, a condition characterized by a low platelet count, which increases the risk of bruising and bleeding. Instructing the client to report any signs of increased bruising or bleeding is crucial for monitoring and managing this potential side effect. Choices A, C, and D are incorrect: A - Increasing potassium-rich foods is not directly related to the side effects of enalapril. C - Developing a cough is a common side effect of ACE inhibitors, but it does not warrant stopping the medication unless advised by a healthcare provider. D - Limiting intake of leafy green vegetables is not necessary with enalapril unless specifically instructed by a healthcare provider for individual reasons.

Correct Answer: C

Rationale: The correct immediate intervention by the nurse in this situation is to push the undiluted 50% dextrose slowly through the current IV infusion. This is because in cases of insulin shock, where the client has dangerously low blood sugar levels, administering 50% dextrose directly into the bloodstream helps rapidly increase blood glucose levels. Choice A is incorrect because diluting the dextrose in one liter of normal saline would delay the administration of glucose, which is needed urgently. Choice B is incorrect as mixing the dextrose in a piggyback solution would also delay the administration of the concentrated dextrose. Choice D is incorrect because adding dextrose to a TPN solution is not the immediate intervention needed to address the low blood sugar levels in a client experiencing insulin shock.

Correct Answer: B

Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, elevated blood pressure is the most concerning finding. Elevated blood pressure can indicate worsening hypertension, which requires immediate intervention to prevent further damage to the kidneys and other organs. Increased fatigue (choice A) is a common symptom in CKD but may not be as acutely concerning as elevated blood pressure. Elevated hemoglobin (choice C) can be an expected outcome of erythropoietin therapy and is not necessarily concerning. Low urine output (choice D) is important to monitor in CKD but may not be as immediately concerning as elevated blood pressure in this context.

Correct Answer: B

Rationale: The correct answer is B. Sleepiness and difficulty feeding are key signs of congenital hypothyroidism, which requires early diagnosis and treatment. Asking about immunizations (choice A) is important but not directly related to assessing hypothyroidism. The feeding method (choice C) is relevant for overall health but not specific to hypothyroidism. Inquiring about relatives with birth defects (choice D) is not the most crucial question to assess hypothyroidism in this scenario.
