Correct Answer: C

Rationale: The correct answer is C because the client stating they should only take the inhaler when feeling short of breath indicates a need for further teaching. Clients with asthma should use their inhaler as prescribed, not just when short of breath. Choices A, B, and D demonstrate good asthma management practices. Choice A indicates understanding of using the albuterol inhaler before exercise to prevent exercise-induced symptoms. Choice B mentions the importance of not overusing the inhaler, which can indicate poor asthma control. Choice D shows awareness of rinsing the mouth after using a corticosteroid inhaler to prevent oral thrush.

Correct Answer: C

Rationale: The correct action the nurse should implement is to apply sequential compression devices to the client's legs. This intervention helps prevent venous stasis and reduce the risk of deep vein thrombosis (DVT). Massaging the client's legs may dislodge a clot and is contraindicated in this situation (choice A). Encouraging bed rest may increase the risk of DVT due to prolonged immobility (choice B). While administering anticoagulants is a common treatment for DVT, in this case, the question is about preventive measures, and using sequential compression devices is a non-pharmacological approach.

Correct Answer: D

Rationale: A glomerular filtration rate of 14 mL/min indicates severe kidney impairment and the need for hemodialysis. The other choices, such as BUN 16 mg/dL, serum magnesium 1.8 mg/dL, and serum phosphorus 4.0 mg/dL, are within normal ranges and do not directly indicate the need for hemodialysis in chronic kidney disease.

Correct Answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

Correct Answer: B

Rationale: Repositioning the client onto her left side is the appropriate intervention when late decelerations are noted on the monitor tracing. This action helps increase uteroplacental blood flow by relieving pressure on the vena cava and aorta, improving fetal oxygenation. Administering oxygen via nasal cannula may be indicated for variable decelerations, not late decelerations. Administering an amnioinfusion is not the primary intervention for late decelerations. Providing reassurance to the client is important but addressing the underlying cause of late decelerations takes precedence.
