A nurse is reviewing the laboratory values for a client who takes spironolactone and notes that the client's serum potassium level is 6.8 mEq/L. The nurse notifies the provider and anticipates that the provider will provide which of the following instructions?
Have the laboratory draw a blood sample for an erythrocyte sedimentation rate
Obtain a 12-lead ECG
Administer potassium gluconate 40 mEq orally
Restrict fluid intake
The Correct Answer is B
Choice A reason : An erythrocyte sedimentation rate (ESR) test is not directly related to high serum potassium levels and would not be the immediate action in response to hyperkalemia.
Choice B reason : Obtaining a 12-lead ECG is a critical step when hyperkalemia is suspected because high potassium levels can cause life-threatening cardiac arrhythmias. An ECG can quickly reveal characteristic changes associated with hyperkalemia, allowing for prompt treatment.
Choice C reason : Administering potassium gluconate would be contraindicated in a patient with hyperkalemia, as it would further increase the serum potassium levels, potentially leading to severe complications.
Choice D reason : Restricting fluid intake is not a standard treatment for hyperkalemia. The management of hyperkalemia may include medications or procedures that promote the excretion of potassium or move potassium from the blood into the cells.

Correct Answer is D
Explanation
Choice A reason: Scheduling the next appointment for 1 year from now is a standard practice for patients who are considered to be in good health and have no immediate medical concerns. Given the patient's normal BP and BMI, along with no reported medical problems, this would typically be an appropriate action. However, it is essential to consider the patient's age and race, as African American men are at a higher risk for certain conditions, such as prostate cancer, which may warrant more frequent monitoring.
Choice B reason: While providing information for a weight loss plan that includes increasing physical activity is generally beneficial, it may not be necessary for this patient. His BMI is 24, which falls within the normal range (18.5-24.9), indicating that he is not overweight. Therefore, unless the patient expresses a desire to lose weight or improve fitness, this action might not be a priority.
Choice C reason:Offering information on reducing risk factors for hypertension is always a positive step in preventive healthcare. However, the patient's BP is 126 mm Hg, which is considered a normal reading (normal BP range is 90/60 mm Hg to 120/80 mm Hg). Therefore, while education on maintaining a healthy lifestyle is valuable, it may not be the most critical action for this visit.
Choice D reason:Scheduling a PSA test is recommended for African American men starting at age 45 due to their increased risk of prostate cancer. The PSA test measures the level of prostate-specific antigen in the blood, which can be an indicator of prostate cancer. Given the patient's demographic, this proactive screening measure is advisable, despite the absence of symptoms or previous medical problems.
Correct Answer is A
Explanation
Choice A reason : In atrial fibrillation, the heartbeat is known to be irregular and often rapid. This irregularity is due to the disorganized electrical signals in the heart's upper chambers, which cause a fast and chaotic heartbeat. Therefore, when documenting the pulse of a client with atrial fibrillation, the term "irregular" is appropriate.
Choice B reason : "Not palpable" would indicate that the pulse cannot be felt, which is not typically the case with atrial fibrillation. While the pulse may be irregular, it is usually still palpable unless the rate is extremely rapid or associated with other complications.
Choice C reason : "Bounding" refers to a pulse that feels strong and full. This is not characteristic of atrial fibrillation. Instead, the pulse in atrial fibrillation may feel weak and irregular due to the ineffective contraction of the atria.
Choice D reason : "Regular" is not an appropriate term to describe the pulse in a client with atrial fibrillation because the condition is characterized by an irregular heart rhythm. The term would be used for a pulse that has consistent beats at regular intervals, which is not the case in atrial fibrillation.
