Correct Answer: D

Rationale: The correct answer is to call for emergency assistance (Option D) when assessing a patient with suspected stroke. Time is crucial in stroke management, and activating emergency services promptly can ensure timely access to specialized care such as stroke units and treatments like thrombolytic therapy. Checking for facial droop (Option A), assessing speech clarity (Option B), and performing a neurological assessment (Option C) are important steps in evaluating a stroke but should follow the immediate action of calling for emergency assistance. These initial assessments can help confirm the suspicion of a stroke and provide valuable information to healthcare providers when they arrive. However, the priority is to ensure the patient receives appropriate care without delay by activating emergency services.

Correct Answer: A

Rationale: The correct answer is A: "Left-sided: Pulmonary congestion; Right-sided: Systemic edema." Left-sided heart failure primarily affects the lungs, leading to pulmonary congestion, which manifests as symptoms like shortness of breath and cough. On the other hand, right-sided heart failure causes systemic congestion and edema, often presenting as swelling in the legs and abdomen due to fluid retention. Choice B is incorrect because it swaps the features of left-sided and right-sided heart failure. Choice C is incorrect as it also incorrectly switches the characteristics of the two types of heart failure. Choice D is incorrect because it inaccurately associates left-sided heart failure with pulmonary congestion and right-sided heart failure with heart failure itself, which is not a distinguishing feature.

Correct Answer: C

Rationale: The correct instruction for a client with left-leg weakness using a cane is to maintain two points of support on the floor at all times. This technique provides stability and support while walking. Choice A is incorrect because the cane should be used on the stronger side to support the weaker leg. Choice B is incorrect as advancing the cane and the strong leg together may not provide adequate support and balance. Choice D is incorrect as the distance to advance the cane with each step can vary depending on the individual's needs and abilities.

Correct Answer: B

Rationale: The correct answer is B because the client should press the button when feeling fetal movement to track the baby's activity. Choice A is incorrect because the client should press the button during movements. Choice C is incorrect as the button should be pressed during fetal movements, not contractions. Choice D is irrelevant to the instructions for the nonstress test.

Correct Answer: B

Rationale: The correct intervention for a client with COPD is to encourage pursed-lip breathing. Pursed-lip breathing helps improve oxygenation by preventing airway collapse, slowing down the breathing rate, and promoting better gas exchange. Administering oxygen at 2L/min via nasal cannula is not the first-line intervention as it can cause oxygen toxicity in COPD patients. Positioning the client in high Fowler's position may improve ventilation but does not specifically address the breathing technique required for COPD. Encouraging deep breathing and coughing is generally not recommended for clients with COPD as it can lead to air trapping and increased work of breathing.
