For a client with diabetes mellitus, which new lab finding is the greatest concern?

Potassium 5.0 mEq/L.

Creatinine 4.4 mg/dL.

Hemoglobin 10.7 g/dL.

Blood Urea Nitrogen (BUN) 22 mg/dL.

Answer and Explanation

The Correct Answer is D

Choice A Reason
A potassium level of 5.0 mEq/L is at the upper limit of the normal range, which is typically between 3.5 and 5.0 mEq/L. While this level should be monitored, especially in the context of diabetes where the patient may be at risk for hyperkalemia due to potential kidney issues, it is not immediately alarming¹.

Choice B Reason
A creatinine level of 4.4 mg/dL is significantly higher than the normal range of 0.6 to 1.2 mg/dL for males and 0.5 to 1.1 mg/dL for females. This indicates severe renal impairment or kidney failure, which is a serious complication of diabetes mellitus. Immediate intervention is required to address this critical issue¹.

Choice C Reason
A hemoglobin level of 10.7 g/dL is slightly below the normal range for adults, which is generally 13.8 to 17.2 g/dL for males and 12.1 to 15.1 g/dL for females. This could indicate mild anemia, which can be a complication of diabetes but is not as immediately concerning as a high creatinine level¹.

Choice D Reason
A Blood Urea Nitrogen (BUN) level of 22 mg/dL is within the normal range, which is typically between 7 and 20 mg/dL. This level does not indicate immediate concern and is not as critical as the elevated creatinine level¹.

Correct Answer is C

Explanation

Choice A reason:
Administering an antiemetic is an important intervention in the PACU, especially if the patient is experiencing nausea or has a history of postoperative nausea and vomiting (PONV). However, it is not the first priority. Antiemetics work by blocking the neurotransmitters that trigger the vomiting reflex. Medications such as ondansetron or promethazine may be used.

Choice B reason:
Applying sequential compression devices is a preventive measure against deep vein thrombosis (DVT), which is a risk due to immobility after surgery. These devices help improve venous return from the lower limbs by applying intermittent pressure. While important, this intervention follows after the assessment of vital signs.

Choice C reason:
Assessing vital signs is the first and foremost priority when a patient is transferred to the PACU. Vital signs, including blood pressure, heart rate, respiratory rate, and oxygen saturation, provide immediate information about the patient's hemodynamic status and can indicate the need for urgent interventions. Any evidence of respiratory or circulatory compromise requires immediate attention.

Choice D reason:
Hanging the Lactated Ringers solution is part of managing the patient's fluid status postoperatively. Lactated Ringers is an isotonic solution that helps to replace lost fluids and maintain electrolyte balance. While important for patient care, it is not the initial priority upon arrival in the PACU.

A. Assess if the client's urine output has increased. B. Ask the client if chest pain is relieved. C. Take the client's blood pressure. D. Ask the client to ambulate and assess for the absence of dyspnea.

Correct Answer is B

Explanation

Choice A Reason
Increased urine output is not a direct indicator of the effectiveness of nitroglycerin for angina pectoris. Nitroglycerin is a vasodilator used primarily to relieve chest pain by improving blood flow to the heart muscle, not to influence urine production.

Choice B Reason
Asking the client if their chest pain has been relieved is the most direct method of evaluating the effectiveness of nitroglycerin. Relief of chest pain indicates that the medication is working as intended, reducing the ischemia that causes angina.

Choice C Reason
While taking the client's blood pressure is important, especially since nitroglycerin can cause hypotension, it is not the primary method for evaluating the effectiveness of the medication in relieving angina. Blood pressure measurements are more of a safety check to monitor for adverse effects.

Choice D Reason
Ambulation and assessing for the absence of dyspnea can be part of an overall evaluation of the client's cardiovascular status, but they are not specific to evaluating the effectiveness of nitroglycerin for angina relief. Dyspnea may be a symptom of heart failure or other conditions, not specifically angina pectoris.
