The nurse administers an antibiotic for a respiratory tract infection. To evaluate the medication's effectiveness, which laboratory values should the nurse monitor?

Correct Answer: B

Rationale: The correct answer is B: White blood cell count and sputum culture. Monitoring white blood cell count and sputum cultures is essential to assess the effectiveness of the antibiotic in treating the respiratory tract infection. Changes in white blood cell count can indicate the body's response to infection, while sputum cultures help determine if the antibiotic is targeting the specific pathogens causing the infection. Choices A, C, and D are incorrect because platelet count, red blood cell count, hemoglobin A1c, glucose tolerance test, arterial blood gases, and serum electrolytes are not directly related to evaluating the effectiveness of an antibiotic in treating a respiratory tract infection.

Correct Answer: D

Rationale: The correct sequence of pathophysiological events in the development of atherosclerosis starts with arterial endothelium injury causing inflammation. This inflammation triggers the formation of foam cells by macrophages consuming low-density lipoprotein (LDL). Subsequently, smooth muscle grows over fatty streaks, creating fibrous plaques. Therefore, option D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate chronological order of events in the pathogenesis of atherosclerosis.

Correct Answer: B

Rationale: The most important dietary instruction for a client with renal disease is to limit fluid intake to 1500 ml/day. This is essential to prevent fluid overload, manage electrolyte balance, and reduce strain on the kidneys. Choice A is incorrect because while protein restriction may be necessary in some cases, avoiding all protein-rich foods is not recommended as some protein intake is essential for overall health. Choice C is incorrect because increasing potassium intake is generally not advised for clients with renal disease, as they often need to limit potassium intake. Choice D is also incorrect because while consuming small, frequent meals may be helpful, emphasizing a diet high in carbohydrates is not typically the primary focus for clients with renal disease.

Correct Answer: C

Rationale: The correct answer is C: Monitor the client's partial thromboplastin time (PTT). During heparin therapy for DVT, it is essential to monitor the PTT to assess the effectiveness of the medication in preventing clot formation. Monitoring the PTT helps ensure that the client is within the therapeutic range for anticoagulation. Choices A, B, and D are incorrect because liver function tests, prothrombin time (PT), and red blood cell count are not specifically monitored to assess the effectiveness of heparin therapy in preventing clot formation.

Correct Answer: C

Rationale: The best intervention for a client with dysphagia experiencing difficulty swallowing medications is to consult with the healthcare provider about switching to liquid medications. Liquid medications are often easier to swallow and can reduce the risk of choking and aspiration in clients with dysphagia. Crushing medications can alter their effectiveness, encouraging the client to drink water may not be sufficient, and offering soft foods is not directly related to improving medication swallowing.
