Correct Answer: C

Rationale: The correct answer is C: Body temperature. In a patient who has fallen through the ice, hypothermia is a major concern due to exposure to cold water. Assessing body temperature first is crucial to determine the severity of hypothermia and guide immediate interventions. Heart rate, breath sounds, and level of consciousness can be affected by hypothermia but are secondary assessments. Assessing body temperature is the priority to address the most life-threatening issue first.

Correct Answer: B

Rationale: The correct answer is B because it acknowledges and validates the patient's belief, showing empathy and support. By stating that the belief gives strength, the nurse facilitates a therapeutic relationship and promotes the patient's emotional well-being. Choice A is incorrect as it challenges the patient's belief system, potentially creating conflict. Choice C is inappropriate as it dismisses the patient's belief and could damage the nurse-patient relationship. Choice D is also incorrect as it invalidates the patient's belief and could harm trust and rapport.

Correct Answer: B

Rationale: The correct answer is B: Administer anticholinergic medications as prescribed. Anticholinergic medications can help dry up secretions and improve breathing in a patient nearing death. This intervention targets the underlying cause of increased secretions. Suctioning (choice A) may provide temporary relief but does not address the root issue. Elevating the head of the bed and repositioning (choice C) can help with comfort but do not directly address the secretions. Restricting oral intake (choice D) may lead to dehydration and discomfort without effectively managing the secretions. Administering anticholinergic medications is the priority as it directly targets the symptom of increased secretions, improving the patient's comfort and quality of life.

Correct Answer: B

Rationale: The correct answer is B: Intravenous fluids. In the scenario of a small bowel obstruction, a PAOP of 1 mm Hg indicates hypovolemia requiring fluid resuscitation to improve cardiac output and tissue perfusion. The low urine output suggests inadequate renal perfusion, further supporting the need for fluids. Diuretics (choice A) would worsen the hypovolemia. Negative inotropic agents (choice C) decrease cardiac contractility, which is not indicated in this scenario. Vasopressors (choice D) are used for hypotension, not for hypovolemia. Therefore, the most appropriate intervention is to administer intravenous fluids to address the hypovolemia and improve tissue perfusion.

Correct Answer: A

Rationale: The correct answer is A: Inflate the balloon for no more than 8 to 10 seconds while noting the waveform change. This is because inflating the balloon within this time frame allows for accurate measurement of PAOP without causing complications like pulmonary edema. Noting the waveform change helps in determining the accurate pressure reading. Explanation of why other choices are incorrect: B: Inflating the balloon with air and recording the volume necessary is not a recommended practice as it can lead to inaccurate readings and potential harm to the patient. C: Maintaining the balloon inflated for 8 hours following insertion is unnecessary and could lead to complications such as vascular damage or thrombosis. D: Zero referencing and leveling the transducer at the phlebostatic axis are important steps but not directly related to performing an initial PAOP measurement.
