Correct Answer: A

Rationale: Idiopathic thrombocytopenic purpura (ITP) is characterized by an autoimmune response that leads to a decreased platelet count. This condition increases the risk of bleeding due to the low platelet levels. Monitoring the platelet count is crucial in managing ITP, as it helps determine the risk of bleeding and guides treatment decisions. Therefore, the correct finding to expect in a client with ITP is a decreased platelet count. Choice B, an increased erythrocyte sedimentation rate (ESR), is not typically associated with ITP. Choice C, decreased megakaryocytes, may be seen in conditions like aplastic anemia but are not a typical finding in ITP. Choice D, an increased white blood cell count (WBC), is not a characteristic feature of ITP.

Correct Answer: C

Rationale: Unilateral breast pain can be a sign of mastitis, an infection of the breast tissue, which requires prompt evaluation and treatment. The nurse should instruct the client to report this clinical manifestation to the provider to prevent complications and promote recovery.

Correct Answer: A

Rationale: Levonorgestrel is an emergency contraceptive that works by inhibiting ovulation to prevent conception. It is most effective when taken as soon as possible within 72 hours following unprotected sexual intercourse. Therefore, the nurse should instruct the adolescent to take the medication promptly to maximize its effectiveness. Choice B is incorrect because levonorgestrel can be used even if the individual is on oral contraceptives. Choice C is incorrect as the efficacy of levonorgestrel is not determined by the onset of menstruation. Choice D is incorrect because levonorgestrel is a single-dose emergency contraceptive and does not provide protection for 14 days after ingestion.

Correct Answer: D

Rationale: During pregnancy, decreased urine output can be indicative of decreased renal perfusion and impaired fetal well-being. It can also be a sign of preeclampsia when associated with symptoms like increased blood pressure, proteinuria, and decreased fetal activity. Therefore, the nurse should promptly report this finding to the healthcare provider for further evaluation and management. Leukorrhea is a common finding in pregnancy and not typically concerning. Supine hypotension and periodic numbness of the fingers can be managed by changing positions or adjusting posture and are not as urgent as decreased urine output in this context.

Correct Answer: D

Rationale: After an amniocentesis, the priority nursing intervention is to monitor the fetal heart rate (FHR) as the greatest risk to the client and fetus is fetal death. This monitoring helps in early identification of any fetal distress or compromise, allowing prompt intervention to ensure fetal well-being. Checking the client's temperature (Choice A) is not the priority as monitoring the fetus is crucial for immediate assessment. Observing for uterine contractions (Choice B) is important but not the priority after an amniocentesis. Administering Rho(D) immune globulin (Choice C) is typically done to Rh-negative clients after procedures that may lead to fetal-maternal hemorrhage, not immediately after an amniocentesis.
