Correct Answer: B

Rationale: The correct answer is B: ELISA and Western Blot. The rationale is as follows: ELISA (enzyme-linked immunosorbent assay) and Western Blot are specific tests used to confirm HIV infection by detecting antibodies or antigens related to the virus. ELISA is the initial screening test, while Western Blot is the confirmatory test. These tests are highly sensitive and specific for HIV detection. Choice A is incorrect because CD4+ cell count and thymus function are not tests used to confirm HIV infection. They are used to monitor disease progression and immune function in HIV-positive individuals. Choice C is incorrect because B-cell and T-cell count are also not tests used to confirm HIV infection. They are indicators of immune system health but not specific for HIV diagnosis. Choice D is incorrect because while CD4+ and viral load tests are used in monitoring HIV progression, ELISA is the main confirmatory test for HIV diagnosis, and viral load is not typically used for initial

Correct Answer: C

Rationale: The correct answer is C: Tactile agnosia. When assessing a client with a parietal lobe brain tumor, the nurse would expect to assess for tactile agnosia as the parietal lobe is responsible for processing sensory information, including touch and spatial awareness. Tactile agnosia is the inability to recognize objects by touch. This impairment is commonly associated with parietal lobe lesions. Short-term memory impairment (A) is more commonly associated with temporal lobe lesions. Seizures (B) are more commonly associated with frontal lobe lesions. Contralateral homonymous hemianopia (D) is associated with occipital lobe lesions. In summary, the parietal lobe tumor would likely manifest as tactile agnosia due to its role in sensory processing, making it the most relevant assessment finding in this scenario.

Correct Answer: B

Rationale: The correct answer is B: canned tomato juice. Canned tomato juice is high in sodium content, which would not be suitable for a patient on a 2 gm sodium diet for heart failure. Sodium restriction is crucial in managing heart failure to reduce fluid retention and strain on the heart. Whole wheat bread, beef tenderloin strips, and apples are lower in sodium content compared to canned tomato juice, making them more appropriate choices for someone on a low-sodium diet.

Correct Answer: A

Rationale: The correct answer is A: Hyperkalemia. In hemodialysis, potassium levels can be elevated due to impaired renal excretion. High potassium can lead to muscle weakness and numbness. The client's K level of 5.9 mEq/L is above the normal range (3.5-5.0 mEq/L), confirming hyperkalemia. Na, Cl, and Ca levels are within normal limits, ruling out hypernatremia, hypochloremia, and hypocalcemia as the client's primary electrolyte imbalance. Monitoring and managing hyperkalemia are crucial to prevent life-threatening complications like cardiac arrhythmias.

Correct Answer: A

Rationale: The correct answer is A: potassium chloride. In Addisonian crisis, the adrenal glands do not produce enough cortisol and aldosterone. Potassium levels are typically elevated in Addisonian crisis due to decreased aldosterone. Administering potassium chloride can further increase potassium levels, leading to life-threatening cardiac arrhythmias. Hydrocortisone (B) is essential to replace cortisol, normal saline solution (C) helps with volume resuscitation, and fludrocortisone (D) replaces aldosterone. Administering potassium chloride would exacerbate the hyperkalemia in Addisonian crisis.
