Which diagnostic test will be most useful to the nurse in determining whether a client admitted with acute shortness of breath has heart failure?
Serum troponin
Arterial blood gasses
12-lead electrocardiogram
B-type natriuretic peptide
The Correct Answer is D
B-type natriuretic peptide (BNP) is a diagnostic blood test that can be most useful to the nurse in determining whether a client admitted with acute shortness of breath has heart failure.
BNP is a hormone produced by the heart in response to increased pressure and volume in the heart, especially in cases of heart failure. When the heart is under stress, such as in heart failure, it releases BNP into the bloodstream. Elevated levels of BNP are strongly indicative of heart failure, and the test is particularly helpful in differentiating heart failure from other conditions that may present with similar symptoms, such as pulmonary disorders.
When a patient presents with acute shortness of breath, the BNP test can provide valuable information to help guide the diagnosis and treatment. If the BNP level is elevated, it suggests that heart failure is likely the cause of the symptoms, and appropriate interventions can be initiated promptly.
While other diagnostic tests like serum troponin (A) are important for assessing heart damage in conditions like myocardial infarction (heart attack), they may not be as specific for heart failure.
Arterial blood gases (B) are helpful in evaluating gas exchange and acid-base balance, especially in patients with respiratory distress, but they are not specific for diagnosing heart failure.
A 12-lead electrocardiogram (ECG) (C) can provide valuable information about the heart's electrical activity and any signs of acute myocardial infarction or other cardiac abnormalities, but it is not the primary test for diagnosing heart failure. An ECG can support the diagnosis if specific changes suggestive of heart failure are present, but the BNP test provides more direct evidence for heart failure diagnosis.

Correct Answer is D
Explanation
The client taking isosorbide dinitrate/hydralazine (BiDil) and experiencing a headache should be assessed first. Isosorbide dinitrate/hydralazine is a medication combination used to treat heart failure, particularly in African American patients. However, one of the side effects of hydralazine is headaches.
Headache in a client taking this medication may indicate increased blood pressure as a compensatory response to vasodilation. If not addressed promptly, it may lead to worsening heart failure or other complications. Therefore, it is essential to assess the client's blood pressure, signs of worsening heart failure, and evaluate the severity and duration of the headache.
The other options may also require attention:
A) A client taking digoxin with a potassium level of 3.1 mEq/L needs assessment, as hypokalemia can increase the risk of digoxin toxicity. However, the headache in the BiDil client takes priority due to the potential complications related to increased blood pressure.
B) A client taking captopril and experiencing a frequent nonproductive cough may indicate a side effect of the medication. While it should be assessed, it is not as immediately concerning as the headache in the BiDil client.
C) A client taking carvedilol (Coreg) with a heart rate of 58 is within an acceptable range, especially if the client is tolerating it well without symptoms. It may not require immediate assessment unless there are other concerning symptoms.
Correct Answer is ["A","B","D"]
Explanation
A) Potassium: CKD can lead to hyperkalemia (high potassium levels) as the kidneys lose their ability to excrete potassium effectively. Limiting potassium intake helps prevent elevated potassium levels and reduces the risk of cardiac arrhythmias.
B) Calcium: In CKD, impaired kidney function can lead to abnormalities in calcium and phosphorus metabolism, which can result in secondary hyperparathyroidism. Limiting calcium intake can help manage the imbalances in calcium and phosphorus levels.
(D) Phosphorus: Impaired kidney function in CKD leads to decreased phosphate excretion, resulting in hyperphosphatemia (high phosphorus levels). High phosphorus levels can lead to bone disease and other complications, so limiting phosphorus intake is essential.
Iron (C) is not typically limited in the diet of a client with CKD unless they have iron overload or specific conditions that warrant iron restriction.
