The nurse practitioner assesses a client in the physician’s office. Which assessment findings support a suspicion of systemic lupus erythematosus (SLE)?

Correct Answer: B

Rationale: The correct answer is B because the assessment findings of pericarditis, photosensitivity, polyarthralgia, and painful mucous membrane ulcers are classic manifestations of systemic lupus erythematosus (SLE). Pericarditis can present as chest pain aggravated by deep breathing or lying flat, photosensitivity refers to skin rashes triggered by sunlight exposure, polyarthralgia involves joint pain in multiple joints, and painful mucous membrane ulcers are common in the mouth or nose. These findings align with the diagnostic criteria for SLE. Choices A, C, and D are incorrect because they do not align with the typical presentation of SLE. Choice A includes facial erythema which is a common symptom, but the presence of profuse proteinuria, pleuritis, fever, and weight loss are not specific to SLE. Choices C and D include symptoms like weight gain, hypothermia, and edema which are not characteristic of SLE. In summary

Correct Answer: C

Rationale: The normal range of hemoglobin in adult blood is typically between 12-18 g/dL. This range is the most common and widely accepted range based on clinical guidelines and research studies. Hemoglobin levels outside this range may indicate anemia or other health conditions. Choice A (7-11 mg) is too low for normal hemoglobin levels in adults and indicates severe anemia. Choice B (14-20 mg) is slightly higher and could be normal for some individuals, but generally, 12-18 g/dL is the standard range. Choice D (20-26 mg) is too high and may indicate dehydration or other medical conditions.

Correct Answer: D

Rationale: The correct answer is D: Calcium. Calcium is necessary for the chemical clotting process because it plays a crucial role in the activation of various clotting factors, leading to the formation of a blood clot. Without sufficient calcium, the clotting cascade would not be able to proceed effectively. Iron (choice A) is essential for red blood cell production, not clotting. Potassium (choice B) and Sodium (choice C) are important for various physiological functions but are not directly involved in the clotting process.

Correct Answer: C

Rationale: The correct answer is C because using an electric razor instead of a safety razor demonstrates understanding of the risk of injury associated with thrombocytopenia. This action shows practical application of the teaching to prevent bleeding. Choice A only indicates awareness but not necessarily action. Choice B shows knowledge but not necessarily application. Choice D is related to general healthcare knowledge but not directly linked to bleeding prevention in thrombocytopenia.

Correct Answer: C

Rationale: The correct answer is C because an ELISA test for antibodies is crucial to detect HIV infection early. This test can help diagnose HIV before symptoms appear, allowing for early intervention and treatment. Choice A is important but not specific to HIV prevention. Choice B is irrelevant for HIV prevention. Choice D, while important, should not take precedence over getting tested for HIV.
