During the 48 hours after a myocardial infarction (MI), a nurse should assign the highest priority to monitoring the patient for what complication?

Among the given laboratory test results for a client with recently diagnosed hypertension, the most important result to communicate to the health care provider is option (A), "Serum creatinine of 2.8 mg/dL."

Serum creatinine is a measure of kidney function, and a value of 2.8 mg/dL indicates elevated creatinine levels. Elevated serum creatinine is a concerning finding, as it suggests decreased kidney function or kidney impairment. Hypertension can have a significant impact on the kidneys, and kidney damage is a common complication of uncontrolled high blood pressure.

The kidneys play a crucial role in regulating blood pressure by excreting waste products and excess fluids from the body. When kidney function is compromised due to hypertension, it can further worsen the blood pressure control, leading to a vicious cycle of kidney damage and worsening hypertension.

Option (B), "Serum hemoglobin of 14.7 g/dL," is within the normal range and does not indicate an immediate concern related to the client's hypertension.

Option (C), "Blood glucose level of 96 mg/dL," is also within the normal range for blood glucose and may not be directly related to the client's hypertension.

Option (D), "Serum potassium of 4.5 mEq/L," is within the normal range. While potassium levels are essential to monitor, they are not the most critical concern compared to kidney function in this context.

The elevated serum creatinine level suggests a potential complication of hypertension, namely kidney damage or decreased kidney function. Therefore, it is essential to communicate this finding promptly to the health care provider for further evaluation and appropriate management to address the client's kidney health and optimize blood pressure control.

The patient is apneic (not breathing) and has no palpable pulses, indicating a cardiac arrest or severe cardiovascular compromise. In this situation, the most appropriate action for the nurse to take next is to start cardiopulmonary resuscitation (CPR) immediately.

CPR is a life-saving procedure that combines chest compressions and rescue breaths to circulate oxygenated blood to vital organs when the heart is not effectively pumping. In the case of cardiac arrest, early initiation of CPR is critical to improve the chances of survival and minimize potential brain damage.

The heart monitor shows sinus tachycardia, rate 132, which suggests that the electrical impulses are reaching the heart, but the heart is not effectively pumping blood due to the lack of a palpable pulse. This condition requires immediate intervention with CPR rather than other treatments such as synchronized cardioversion (option A) or administering atropine (option D).

While applying supplemental oxygen via a non-rebreather mask (option C) is generally important in many emergency situations, it is not the immediate priority when a patient is apneic and has no palpable pulses. In such cases, CPR takes precedence to restore circulation and maintain oxygen delivery to the body's vital organs.
