Correct Answer: A

Rationale: The correct answer is A: Staphylococcus aureus infections, including MRSA. Severe infections like MRSA are required to be reported to the health department as they pose a significant public health risk. Choices B, C, and D are incorrect because severe flu-like symptoms, common colds, and non-severe respiratory infections, and only contagious diseases like meningitis do not fall under the category of infectious diseases that must be reported to the health department.

Correct Answer: B

Rationale: The correct answer is B because prolonged use of corticosteroids is a known risk factor for infections. Choice A is incorrect because frequent hand washing actually helps prevent infections. Choice C is incorrect as patient interaction is essential in healthcare but should be done following proper infection control measures. Choice D is also incorrect as restricting client movement is not a standard practice to prevent contamination.

Correct Answer: C

Rationale: The correct answer is C: Apply a sequential compression device. Applying a sequential compression device promotes venous return by assisting with blood circulation in the lower extremities, reducing the risk of blood clots. Encouraging deep breathing exercises can help with lung expansion but does not directly promote venous return. Maintaining the client in a supine position may not be ideal for promoting venous return if the client is unable to move. Massaging the client's legs may be contraindicated postoperatively due to the risk of dislodging a clot or causing trauma to the surgical site.

Correct Answer: A

Rationale: Correct answer: To assess a patient with potential diabetic ketoacidosis (DKA), healthcare providers should monitor blood glucose and check for ketones in the urine. Elevated blood glucose levels and the presence of ketones in urine are indicative of DKA. Choice B is incorrect because administering insulin and providing fluids are treatments for DKA rather than assessment measures. Choice C is incorrect as administering potassium and checking for electrolyte imbalance are interventions related to managing DKA complications, not initial assessment. Choice D is incorrect because administering sodium bicarbonate and monitoring urine output are not primary assessment actions for DKA.

Correct Answer: B

Rationale: The correct answer is B: 'Reduce sodium intake to less than 1,500 mg per day.' For clients with hypertension, reducing sodium intake is crucial as it helps manage blood pressure. High sodium intake can lead to fluid retention and increased blood pressure. Choice A is incorrect because increasing sodium intake would worsen hypertension. Choice C is also correct as limiting caffeine intake is beneficial for managing hypertension. Choice D is incorrect as increasing caffeine intake can elevate blood pressure, which is detrimental for clients with hypertension.
