Correct Answer: B

Rationale: The correct answer is B: The specific hormones secreted by the tumor. Pituitary adenomas are known to secrete hormones that can lead to various endocrine disorders. Understanding the specific hormones secreted by the tumor is crucial in determining the clinical manifestations and planning appropriate treatment. Choices A, C, and D are incorrect because the primary determinant of the effects of the tumor in this case is the hormonal activity rather than whether the tumor uses aerobic or anaerobic respiration, the patient's pre-existing health status, or whether the tumor is primary or metastatic.

Correct Answer: A

Rationale: The correct answer is A: Sit or stand in front of the patient when speaking. This choice is correct because it allows the patient with otosclerosis to directly see the nurse's face and lip movements, aiding in lip-reading and understanding speech. Sitting or standing in front of the patient also ensures better eye contact and reduces background noise interference. Choice B is incorrect because exaggerated lip and mouth movements may distort speech and make it harder for the patient to understand. Choice C is incorrect because standing in front of a light or window can create glare and make it difficult for the patient to see the nurse's face clearly. Choice D is incorrect because saying the patient's name loudly before starting to talk does not directly address the communication needs of a patient with otosclerosis.

Correct Answer: B

Rationale: The correct answer is B: Hard boardlike abdomen. In abruptio placentae, concealed hemorrhage can lead to blood accumulating behind the placenta, causing the uterus to become tense and rigid, resulting in a hard boardlike abdomen. This finding indicates significant internal bleeding and requires immediate medical attention. Rationale: A: Bradycardia is a slow heart rate and is not typically associated with concealed hemorrhage in abruptio placentae. C: Decrease in fundal height may indicate intrauterine growth restriction, not specifically concealed hemorrhage. D: Decrease in abdominal pain is not a typical indicator of concealed hemorrhage; in fact, pain may increase due to the increased pressure in the uterus from the bleeding.

Correct Answer: A

Rationale: Step-by-step rationale for why answer A is correct: 1. Ambulating is a crucial postoperative activity to prevent complications like blood clots. 2. Understanding when to ambulate ensures the patient follows proper recovery guidelines. 3. Proper ambulation aids in preventing postoperative complications and promotes healing. Summary of why other choices are incorrect: B. Having someone accompany the patient is important for support but not a strict criteria for discharge. C. While understanding activity restrictions is important, it is not a specific criteria for immediate discharge. D. Understanding care for the biopsy site is essential but not a strict criteria for immediate discharge. E. Removal of a urinary catheter is not typically related to discharge criteria for a breast biopsy.

Correct Answer: A

Rationale: The correct initial action for the school nurse is to assess for signs and symptoms of anaphylaxis (Choice A). This is crucial as anaphylaxis is a severe allergic reaction that can be life-threatening and requires immediate intervention. Assessing for anaphylaxis symptoms such as difficulty breathing, swelling of the face or throat, and a rapid pulse helps the nurse quickly identify the severity of the situation. Administering OTC antihistamines (Choice C) or epinephrine (Choice D) should only be done after confirming the presence of anaphylaxis. Assessing for erythema and urticaria (Choice B) is important but not as immediate as assessing for signs of anaphylaxis in this scenario.
