Correct Answer: C

Rationale: The correct answer is C because firm skin turgor indicates adequate hydration, a key goal of fluid resuscitation in diarrhea management. Firm skin turgor reflects the body's fluid balance and hydration status. When fluid resuscitation is successful, the patient's skin turgor improves due to replenished fluid levels. Choices A, B, and D are incorrect as they do not directly assess hydration status or the effectiveness of fluid resuscitation. Passing formed stools, decrease in stool frequency, and absence of perianal burning may be positive outcomes in diarrhea management, but they do not specifically indicate successful fluid resuscitation.

Correct Answer: A

Rationale: The correct answer is A: Otorrhea. Otorrhea refers to the discharge of fluid from the ear, indicating an abnormal finding of ear drainage. This term specifically describes the symptom of ear drainage, making it the most appropriate choice for documenting this finding. Otalgia (choice B) refers to ear pain, ototoxic (choice C) refers to substances that are harmful to the ear, and tinnitus (choice D) refers to ringing in the ears, none of which accurately describe ear drainage. Therefore, the correct choice is A as it specifically addresses the symptom of ear drainage.

Correct Answer: D

Rationale: The correct answer is D: Platelet count. Zidovudine (AZT) is known to cause bone marrow suppression, leading to decreased platelet production. Monitoring platelet count is crucial to detect early signs of thrombocytopenia, a common adverse effect of AZT. Rationale: A) RBC count: AZT can cause anemia, not specifically affecting the RBC count. B) Serum calcium: AZT does not typically affect calcium levels. C) Fasting blood glucose: AZT can cause hyperglycemia, but fasting blood glucose monitoring is not as critical as monitoring platelet count for AZT therapy.

Correct Answer: C

Rationale: The correct answer is C because subjective data refers to information provided by the patient based on their feelings, perceptions, and experiences. In this case, the patient describing excitement about discharge is subjective data as it reflects the patient's emotional state. The other choices, A, B, and D, are considered objective data because they are observable and measurable by the nurse. The patient's temperature can be measured (A), the wound appearance can be visually assessed (B), and the patient pacing the floor is an observable behavior (D). Therefore, these choices are not subjective data.

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.
