A client comes to the clinic complaining of weight loss, fatigue, and a low-grade fever. Physical examination reveals a slight enlargement of the cervical lymph nodes. To assess possible causes for the fever, it would be most appropriate for the nurse to initially ask: a."Have you bee sexually active lately?" b, "Do you have a sore throat at the present time?"

Correct Answer: A

Rationale: Rationale: - The correct answer is A, "Have you been exposed recently to anyone with an infection?" because it helps assess potential sources of infection causing the low-grade fever and other symptoms. - Choice B is irrelevant as the client's current sore throat is not the main concern. - Choice C and D do not address the potential infectious etiology of the symptoms. - Overall, assessing recent exposure to infections is crucial in identifying possible sources of the client's symptoms.

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: To stimulate bone growth. Estrogen and progesterone are hormones that play a crucial role in maintaining bone density and promoting bone growth. In postmenopausal women or individuals with conditions like aplastic anemia, bone health can be compromised. Estrogen helps in preventing bone loss and maintaining bone strength, while progesterone also contributes to bone formation. Therefore, in this scenario, these medications are likely prescribed to help improve bone health in the woman with aplastic anemia. Incorrect choices: B: Estrogen and progesterone do not directly enhance sodium and potassium levels. C: Estrogen and progesterone do not regulate fluid balance absorption directly. D: Estrogen and progesterone do not specifically promote utilization and storage of fluids.

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: Probenecid (Benemid). Probenecid can increase methotrexate levels, leading to potential toxicity. Methotrexate is primarily eliminated by the kidneys, and Probenecid inhibits renal tubular secretion, causing methotrexate levels to rise. Digoxin (A), theophylline (C), and famotidine (D) do not have significant interactions with methotrexate. In summary, Probenecid is the correct answer as it can increase methotrexate levels through renal tubular secretion inhibition, while the other choices do not have a significant interaction with methotrexate.
