How should a healthcare provider respond to a patient who is exhibiting signs of acute myocardial infarction (AMI)?

Correct Answer: A

Rationale: When a patient is exhibiting signs of acute myocardial infarction (AMI), the priority action is to call for emergency assistance immediately. This ensures that the patient receives prompt and appropriate care, including interventions such as administering oxygen, nitroglycerin, and monitoring cardiac rhythm. Administering nitroglycerin should only be done if prescribed by a healthcare provider after assessment and confirmation of AMI. Monitoring the patient's cardiac rhythm is important but not the initial action needed in this critical situation. Administering oxygen and preparing for an ECG are important interventions but should follow the immediate step of calling for emergency assistance.

Correct Answer: D

Rationale: The correct answer is D: Tachycardia, hypotension, and decreased urine output are classic clinical manifestations of hypovolemic shock. In hypovolemic shock, the body tries to compensate for low blood volume by increasing the heart rate (tachycardia) to maintain cardiac output, leading to hypotension and decreased urine output. Prompt fluid replacement is necessary to restore intravascular volume. Choices A, B, and C are incorrect because they do not represent the typical manifestations of hypovolemic shock.

Correct Answer: B

Rationale: Verifying the patient's identity before administration is a critical step to ensure that the correct blood product is given to the right patient, thereby preventing transfusion errors. While ensuring proper documentation of the transfusion (choice A) is important for record-keeping, verifying patient identity (choice B) directly addresses the risk of administering blood to the wrong patient. Monitoring for allergic reactions or transfusion reactions (choice C) and monitoring the patient's vital signs during transfusion (choice D) are also essential considerations during blood product administration, but verifying patient identity takes precedence to prevent potentially life-threatening errors.

Correct Answer: A

Rationale: The correct nursing intervention for a patient with acute kidney injury (AKI) includes preparing the patient for dialysis if necessary. While choices B, C, and D are also important aspects of managing AKI, the critical intervention in severe cases is to prepare the patient for dialysis to support kidney function. Providing dietary modifications to reduce potassium, monitoring urine output and electrolytes, and administering fluids are essential components of the overall care plan for AKI patients, but in cases where the condition is severe or if conservative management fails, dialysis may be required to support the patient's kidney function and prevent further complications.

Correct Answer: A

Rationale: The correct answer is A: Checking tube placement before administration. This is a crucial step to ensure that the medication reaches the stomach safely and does not end up in the lungs, which can lead to serious complications. Choice B is incorrect as not all medications can be administered in liquid form. Choice C is incorrect because crushing tablets can alter their effectiveness or cause harm. Choice D is incorrect as flushing the NG tube with water is not a standard practice before administering medication, unless specified by healthcare provider instructions.
