To evaluate the effectiveness of nitroglycerin 0.4 mg SL administered to a client diagnosed with angina pectoris, the nurse should:
Assess if the client's urine output has increased.
Ask the client if chest pain is relieved.
Take the client's blood pressure.
Ask the client to ambulate and assess for the absence of dyspnea.
The Correct Answer is B
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.

Correct Answer is B
Explanation
Choice a reason:
A cream to soothe itching may be used if the client is experiencing pruritus, which can sometimes accompany biliary issues due to bile salts in the skin. However, pruritus is not a direct symptom of biliary colic, which is characterized primarily by pain.
Choice b reason:
Pain medication is the appropriate treatment for biliary colic. Biliary colic is caused by the temporary blockage of the bile duct by a gallstone, leading to intense pain in the upper right abdomen or the center of the abdomen. Pain relief is typically achieved with anti-inflammatory drugs or antispasmodics, and in some cases, opioids may be necessary.
Choice c reason:
An antibiotic would be prescribed if there was an infection, such as cholecystitis or cholangitis. Biliary colic itself does not necessarily indicate an infection unless accompanied by other symptoms such as fever or elevated white blood cell count.
Choice d reason:
A laxative is not typically used to treat biliary colic. While laxatives can help relieve constipation, biliary colic is a result of gallstones obstructing the bile duct, not bowel movement issues.
Correct Answer is D
Explanation
Choice a reason:
An increase in urine output can be a sign of improved kidney function or the effect of medications, but it is not a direct indicator of reduced cardiac workload. Atenolol, a beta-blocker, primarily reduces the heart rate and myocardial oxygen demand, not urine output.
Choice b reason:
Less dyspnea with activity suggests improved cardiovascular efficiency, but it is not a specific measure of cardiac workload. Dyspnea can be influenced by respiratory conditions and is not solely determined by cardiac function.
Choice c reason:
A blood pressure of 120/80 mmHg is considered optimal for most adults and indicates good control of hypertension. However, it does not specifically reflect the cardiac workload, which is more directly affected by heart rate and myocardial oxygen demand.
Choice d reason:
A heart rate of 65 per minute is a clear indicator that atenolol is effective in reducing cardiac workload. Atenolol decreases the heart rate, which in turn reduces myocardial oxygen demand and the overall workload on the heart. This is particularly important for patients with unstable angina, where reducing the heart's workload can prevent angina attacks and potential myocardial infarction.
