What are the key components of a focused respiratory assessment, and how do you recognize signs of respiratory distress?

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: A

Rationale: The correct procedure for inserting a nasogastric (NG) tube involves measuring the tube to ensure the appropriate length for insertion and using lubrication to reduce discomfort and aid in smooth insertion. Choice B is incorrect as measuring the tube is essential for proper placement. Choice C is incorrect as lubrication helps in easing the insertion process. Choice D is incorrect as checking the placement comes after insertion and should not be done simultaneously with the insertion process.

Correct Answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.

Correct Answer: A

Rationale: The correct way to assess for pitting edema is to press over a bony area, typically the tibia, for 5 seconds and then release. This allows for the identification of pitting edema, characterized by an indentation that persists for a few seconds. Choice B is incorrect as pitting edema assessment does not involve checking for discoloration. Choice C is incorrect as the presence of a rash is not indicative of pitting edema. Choice D is incorrect as rebound tenderness is a different assessment used for abdominal conditions, not for pitting edema.

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.
