The health care provider diagnoses impetigo in a patient who has crusty vesicopustular lesions on the lower face. Which instructions should the nurse include in the teaching plan?

Correct Answer: A

Rationale: The correct answer is A: Clean the infected areas with soap and water. This is because impetigo is a bacterial skin infection that requires good hygiene to prevent spreading. Cleaning the infected areas with soap and water helps to remove bacteria and crusty discharge. Choice B is incorrect because alcohol-based cleansers can be too harsh and irritating to the skin, further aggravating the lesions. Choice C is also incorrect as antibiotic ointments are commonly used to treat impetigo by killing the bacteria causing the infection. Choice D is incorrect because using petroleum jelly may trap bacteria and moisture, worsening the infection. It is important to keep the affected areas clean and dry to promote healing.

Correct Answer: B

Rationale: The correct answer is B (38-year-old with a 7-mm nevus on the face that has recently become darker) because changes in the color, shape, or size of a mole could indicate melanoma, a type of skin cancer. This patient's symptoms require immediate evaluation. Choice A (50-year-old with skin redness after a chemical peel) is likely post-inflammatory erythema, which is a common side effect and not an urgent issue. Choice C (62-year-old with papules in axillary areas) is likely skin tags, which are benign and not urgent. Choice D (42-year-old with itching after using topical fluorouracil) is a common side effect and can usually wait for a regular appointment.

Correct Answer: A

Rationale: The correct answer is A: Lift the patient's leg to a 60-degree angle from the bed. This is because the straight-leg raising test is used to assess for sciatic nerve irritation. Lifting the leg to a 60-degree angle from the bed helps to stretch the sciatic nerve and can elicit pain if there is nerve compression. Placing the patient in the prone position (B) or asking the patient to dangle both legs (C) would not provide the proper positioning for this test. Instructing the patient to elevate the legs and tense the abdominal muscles (D) is not the correct technique for performing the straight-leg raising test.

Correct Answer: A

Rationale: The correct answer is A because using a keyboard pad can help support the wrist and reduce strain during typing, promoting proper ergonomics. This can prevent wrist injuries and musculoskeletal issues. Stretching exercises (B) can be beneficial but may not address the root cause of the issue. Wrapping wrists with compression bandages (C) can restrict movement and may not be necessary for prevention. Avoiding NSAIDs (D) may not be necessary as a preventive measure unless prescribed by a healthcare provider for a specific reason.

Correct Answer: A

Rationale: The correct answer is A: Notify the health care provider. In this scenario, the patient's severe pain, faint pulses, and cool foot suggest a potential complication such as compartment syndrome, which is a medical emergency. Notifying the health care provider immediately is crucial for prompt evaluation and intervention to prevent further complications. Repositioning the leg on pillows (choice C) may worsen the condition, assessing the incision for redness (choice B) is not the priority in this situation, and checking the patient's blood pressure (choice D) does not directly address the urgent issue at hand.
