What is the correct procedure for inserting a nasogastric (NG) tube?

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 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.

Correct Answer: A

Rationale: The correct answer is A: Inspection, Palpation, Percussion, Auscultation. A focused respiratory assessment involves inspecting the chest for any abnormalities, palpating to assess tenderness and chest expansion, percussion to evaluate underlying structures, and auscultation to listen to lung sounds. Choice B is incorrect because observation is generally part of inspection, not a separate component. Choice C is incorrect as auscultation should come before percussion in a respiratory assessment. Choice D is incorrect because inspection should precede palpation in a structured assessment.

Correct Answer: A

Rationale: The correct answer is A: Fever, chills, and increased heart rate are classic signs of an infection. These symptoms indicate the body's response to an invading pathogen. Choice B, 'Increased white blood cell count and fever,' is not a primary symptom that a person would typically notice themselves, and white blood cell count needs to be tested. Choice C, 'Shortness of breath and confusion,' may indicate other conditions like heart or lung issues rather than a general infection. Choice D, 'Sweating and low blood pressure,' are not specific to infections and can be caused by various factors like heat or dehydration.
