Correct Answer: B

Rationale: The correct answer is to instill the first dose of nystatin vaginally per applicator. Nystatin is an antifungal medication used to treat yeast infections, which are characterized by 'cottage cheese' discharge. Cleansing the perineum with warm soapy water may help with hygiene but does not address the underlying infection. Performing a glucose measurement is not relevant to the diagnosis of a vaginal infection. Obtaining a blood specimen for STDs is not the priority in this scenario as the symptoms described are indicative of a yeast infection.

Correct Answer: A

Rationale: The correct intervention for a child with Leukemia undergoing chemotherapy and experiencing altered nutrition, less than body requirements due to anorexia, nausea, and vomiting is to allow the child to eat foods desired and tolerated. This intervention helps improve the child's nutrition intake during chemotherapy. Choice B is incorrect because restricting foods may further limit the child's nutritional intake. Choice C is incorrect because recommending eating the same foods as siblings may not align with the child's preferences or needs during treatment. Choice D is incorrect as encouraging large portions of food at every meal may overwhelm the child and be counterproductive to their nutritional needs.

Correct Answer: D

Rationale: The correct instruction for an elderly client taking both an ACE inhibitor and a calcium channel blocker is to change positions slowly. Both medications can lead to orthostatic hypotension, a sudden drop in blood pressure when changing positions, which can increase the risk of falls. Instructing the client to change positions slowly helps prevent falls. Wearing long-sleeved clothing when outdoors does not directly relate to the medication combination. Reporting the onset of a sore throat is important for monitoring potential side effects but is not specific to these medications. While potassium levels should be monitored with ACE inhibitors, eating plenty of potassium-rich foods without guidance can lead to hyperkalemia, a potential side effect of ACE inhibitors.

Correct Answer: C

Rationale: The correct action for the nurse to take first when a client with COPD reports difficulty breathing while receiving oxygen is to check the client's oxygen saturation level. This helps in determining the adequacy of oxygenation and identifying the cause of the breathing difficulty. Increasing the oxygen flow rate (Choice A) may not be appropriate without knowing the current oxygen saturation level. Instructing the client to breathe deeply and cough (Choice B) may not address the immediate need for oxygen assessment. Placing the client in a high-Fowler's position (Choice D) can help with breathing but should come after ensuring proper oxygenation.

Correct Answer: A

Rationale: The correct action for a client with type 1 diabetes mellitus experiencing hypoglycemia with a blood glucose level of 60 mg/dl is to administer 15 grams of carbohydrate. This will help raise the blood glucose levels quickly. Administering a glucagon injection (Choice B) is usually reserved for severe hypoglycemia where the client is unconscious or unable to swallow. Providing a snack with protein (Choice C) is not the first-line treatment for hypoglycemia as protein takes longer to raise blood glucose levels. Encouraging the client to rest (Choice D) may be beneficial after administering the carbohydrate, but the priority is to raise the blood glucose levels promptly.
