Correct Answer: B

Rationale: The correct answer is B: Look at the patient when talking. This is important because maintaining eye contact shows respect, builds trust, and enhances communication with the patient. By looking at the patient, the nurse can also observe nonverbal cues and ensure the patient is engaged in the conversation. Choice A: Using long sentences can be overwhelming for a patient who may not understand the language, leading to miscommunication. Choice C: Using breaks in sentences may help the interpreter better convey the message, but looking at the patient is more essential for effective communication. Choice D: Looking at only nonverbal behaviors neglects the importance of eye contact and direct communication with the patient.

Correct Answer: B

Rationale: The correct answer is B: Administration of methotrexate. This is the priority intervention for an intact tubal pregnancy to prevent further growth and potential rupture of the fallopian tube. Methotrexate is a medication used to stop the growth of the pregnancy tissue. Assessment of pain level (A) is important but not the priority as immediate intervention to address the ectopic pregnancy is crucial. Administration of Rh immune globulin (C) is not the priority in this situation, as it is typically given after a miscarriage or abortion to prevent Rh sensitization. Explanation of common side effects (D) is important for patient education, but it is not the immediate priority when dealing with an ectopic pregnancy.

Correct Answer: B

Rationale: The correct answer is B. By asking the patient to demonstrate the instillation of medications, the nurse can directly assess the patient's ability to self-administer the medications safely and effectively. This method allows for a practical demonstration of skills, which is more reliable than relying solely on verbal descriptions or past experiences. Choices A, C, and D are incorrect because assessing for previous inability, describing the method, or evaluating functional status may not directly demonstrate the patient's competency in self-administering ocular medications.

Correct Answer: A

Rationale: The correct answer is A: immediate birth is required. The Kleihauer–Betke test is used to detect fetal-maternal hemorrhage in situations where there is a risk of fetal blood entering the maternal circulation, such as trauma during pregnancy. A positive result indicates a significant fetal-maternal hemorrhage, which can lead to Rh incompatibility and severe fetal anemia. Immediate birth is required to prevent complications and ensure the safety of both the mother and the baby. Choice B is incorrect as transferring the patient to the critical care unit does not address the underlying issue of fetal-maternal hemorrhage. Choice C is incorrect as RhoGAM is typically administered to prevent Rh sensitization in Rh-negative mothers carrying Rh-positive babies, which is not the primary concern in this scenario. Choice D is incorrect as a tetanus shot is not directly related to the positive Kleihauer–Betke test result indicating fetal-maternal hemorrhage.

Correct Answer: A

Rationale: The correct answer is A: Drink more water to prevent further dehydration. Given the patient's fair skin turgor, fatigue, weakness, warm and dry skin, elevated pulse rate, and slightly elevated urinary sodium level, these are signs of dehydration. Increasing water intake would help improve the patient's hydration status. Other choices are incorrect because B (calorie-dense fluids) does not address the dehydration issue, C (milk and dairy products) does not directly address the symptoms presented, and D (grapefruit juice) is not essential for hydration in this case.
