Correct Answer: A

Rationale: The correct answer is A: Encourage lifestyle modifications and medication adherence. Patient education in hypertension management should focus on encouraging lifestyle changes like a healthy diet, exercise, stress management, and adherence to prescribed medications. Choices B, C, and D are incorrect because advising patients to avoid physical activity, recommending a low-sodium diet, and increasing potassium intake, although related to hypertension management, do not encompass the comprehensive approach needed for effective patient education on this topic.

Correct Answer: B

Rationale: Performing a wound culture before applying ointment is crucial when providing wound care for a client with a pressure ulcer. This step helps identify the presence of any infection, allowing for appropriate treatment. Choice A is incorrect because covering the wound with a dry, sterile dressing may not address potential infections. Choice C is incorrect as cleansing the wound with alcohol can be too harsh and drying to the surrounding skin. Choice D is incorrect because covering the wound with a wet-to-dry dressing is not typically recommended for pressure ulcers, as it can cause trauma to the wound bed during removal.

Correct Answer: A

Rationale: The correct answer is A: Inspection, Palpation, Percussion, Auscultation. A focused respiratory assessment should start with inspection (observing the breathing pattern), followed by palpation (feeling for abnormalities like crepitus), percussion (evaluating for dullness or hyperresonance), and auscultation (listening to lung sounds). This systematic approach helps to identify signs of respiratory distress, such as abnormal breath sounds, increased respiratory rate, use of accessory muscles, and cyanosis. Choices B, C, and D are incorrect because they do not follow the standard order and sequence of a focused respiratory assessment.

Correct Answer: C

Rationale: Pale conjunctiva is a common sign of iron deficiency anemia due to reduced hemoglobin levels. This results in decreased oxygen-carrying capacity, leading to tissue hypoxia and pallor. 'Increased energy' (choice A) is not typically associated with iron deficiency anemia, as fatigue and weakness are common symptoms. 'Easy bruising' (choice B) is more characteristic of platelet disorders or vitamin deficiencies rather than iron deficiency anemia. 'Weight gain' (choice D) is not a typical finding in iron deficiency anemia; in fact, weight loss is more common due to decreased appetite and overall weakness.

Correct Answer: B

Rationale: The correct answer is to ensure oxygen tanks are kept upright at all times. This is important to prevent the tanks from falling over, which can lead to injuries or tank damage. Choice A is incorrect because oxygen tanks should not be stored in a closet when not in use, as this can lead to poor ventilation and potential hazards. Choice C is incorrect because smoking near oxygen tanks poses a significant fire risk. Choice D is incorrect because while it is important to keep oxygen equipment away from heat sources, ensuring the tanks are kept upright is a more critical safety measure.
