What are the principles of aseptic technique in wound care?

Correct Answer: A

Rationale: The correct answer is A: 'Use sterile gloves and a clean dressing.' Aseptic technique in wound care requires the use of sterile gloves to prevent infection. Choice B is incorrect as the method of application does not primarily focus on maintaining asepsis. Choice C, while important for infection control, is not specific to aseptic technique in wound care. Choice D is incorrect because using a single clean glove does not ensure the level of sterility needed for aseptic wound care.

Correct Answer: A

Rationale: When caring for a patient with a nasogastric (NG) tube, it is crucial to check the tube placement and assess for signs of aspiration. This ensures that the tube is correctly positioned and that the patient is not at risk of complications such as aspiration pneumonia. Choice B is incorrect as flushing the tube with water regularly is not a standard practice and may not be appropriate for all patients. Choice C is incorrect as monitoring for bowel sounds is not directly related to NG tube care, and administering medications is not the primary focus of caring for the tube itself. Choice D is incorrect because administering medications through the NG tube is a specific action that may be taken based on a healthcare provider's order, not a general care guideline for the NG tube.

Correct Answer: A

Rationale: Hypokalemia is managed by administering potassium supplements to correct the low potassium levels in the body. Monitoring the ECG is essential because low potassium levels can lead to cardiac arrhythmias. Choice B is incorrect as restricting fluid intake and providing a high-sodium diet are not appropriate for managing hypokalemia. Choice C is incorrect because hypokalemia involves low potassium levels, not sodium levels, and insulin therapy does not directly address this issue. Choice D is incorrect as calcium supplements are not indicated for hypokalemia, and monitoring for hyperkalemia is not relevant in this case.

Correct Answer: A

Rationale: The correct answer is A: Inspection, Palpation, Percussion, Auscultation. A focused respiratory assessment involves inspecting the chest for symmetry and signs of distress, palpating for tenderness or abnormal masses, performing percussion to assess underlying tissues, and auscultating lung sounds. Choice B is incorrect as observation is a broad term that can encompass both inspection and palpation. Choice C is incorrect as auscultation is usually performed after inspection and palpation. Choice D is incorrect as observation should be more specific, and auscultation is a key component that is typically done last in a respiratory assessment.

Correct Answer: A

Rationale: The correct nursing interventions for a patient with hypertension involve monitoring blood pressure and educating the patient about lifestyle changes. These interventions help in managing hypertension by keeping track of the patient's blood pressure readings and empowering them with knowledge to make lifestyle modifications such as adopting a healthy diet, regular exercise, stress management, and avoiding smoking and excessive alcohol consumption. Administering antihypertensive medications (choice B) is typically done by a healthcare provider rather than a nurse. While regular monitoring of blood pressure (choice C) is important, administering diuretics is a specific medical intervention that should be prescribed by a healthcare provider. Monitoring blood glucose (choice D) is more relevant for patients with diabetes rather than hypertension.
