Correct Answer: A

Rationale: The correct answer is A: Anticholinesterase drugs. These drugs increase acetylcholine levels at neuromuscular junctions, helping improve muscle strength in myasthenia gravis. Adrenergic drugs (B) and beta-blocker drugs (D) are not typically used to treat muscle weakness in myasthenia gravis. Anticholinergic drugs (C) can worsen symptoms by blocking acetylcholine receptors, making them an inappropriate choice for this condition.

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: A

Rationale: The correct answer is A: Pregnancy. During pregnancy, the need for iron increases significantly to support the growth of the fetus and to prevent maternal anemia. Iron is essential for the production of hemoglobin and for oxygen transport in the blood. In contrast, infants require iron for rapid growth and development, making choice B partially correct. Choice C (Old age) and choice D (Male reproductive years) are incorrect as the need for iron typically decreases in old age and remains relatively stable during male reproductive years.

Correct Answer: A

Rationale: The correct answer is A: Identify factors interfering with goal achievement. This is the priority action because it focuses on understanding what caused the patient to fall despite the goal of preventing falls. By identifying the factors interfering with goal achievement, the nurse can make necessary adjustments to the care plan to prevent future falls. Choice B is incorrect because counseling the nursing assistive personnel and removing the fall risk sign does not address the root cause of the fall. Choice C is incorrect because shifting responsibility to the charge nurse for documentation does not address the immediate need to assess and address the factors contributing to the fall. Choice D is incorrect because documenting the fall is important but not the priority when the immediate concern is understanding why the fall occurred.

Correct Answer: C

Rationale: Rationale: 1. Loratadine is typically dosed once daily, not twice daily, for allergic rhinitis. 2. Taking it twice daily may increase the risk of side effects without added benefit. 3. The client's dosing schedule reflects a misunderstanding of the medication regimen. 4. Option A is incorrect because loratadine is available in 10mg tablets. 5. Option B is incorrect as loratadine can be taken with or without food. 6. Option D is incorrect as Claritin is a common trade name for loratadine.
