To evaluate the effectiveness of nitroglycerin 0.4 mg SL administered to a client diagnosed with angina pectoris, the nurse should:

Choice a reason:
Including yogurt in the diet can be beneficial for a client experiencing diarrhea related to antibiotic therapy. Yogurt contains probiotics, which are live microorganisms that can provide health benefits when consumed. These probiotics can help restore the balance of good bacteria in the gut that antibiotics may have disrupted, potentially reducing the duration and severity of diarrhea. However, it's important to choose yogurts that contain active probiotics and to be aware that some individuals may not tolerate dairy well during a bout of diarrhea.

Choice b reason:
Administering famotidine 20 mg daily may help with symptoms of gastritis or peptic ulcers but is not directly related to treating antibiotic-associated diarrhea. Famotidine is a histamine-2 blocker used to reduce stomach acid and is not typically used as a treatment for diarrhea. It should be noted that if a patient is experiencing severe diarrhea, the underlying cause should be addressed rather than just managing symptoms.

Choice c reason:
Testing stool for occult blood is generally not a standard intervention for antibiotic-related diarrhea unless there is a suspicion of gastrointestinal bleeding or an infection like C. difficile, which can cause more severe colitis. Occult blood tests are more commonly used for screening for colorectal cancer or diagnosing conditions that cause gastrointestinal bleeding.

Choice d reason:
Arranging for IV administration of the antibiotic instead of the oral route may be considered if the client has severe diarrhea that prevents the absorption of oral medications or if the client is unable to tolerate oral intake[^10^]¹¹¹²¹³¹⁴. However, many antibiotics have excellent oral bioavailability, and switching from IV to oral antibiotics when appropriate can be just as effective and is often preferred due to convenience and lower risk of complications.

Choice a reason:
Bleeding at the arterial puncture site is a primary concern post-cardiac angiogram, as it can lead to significant blood loss and hematoma formation. The nurse must frequently monitor the site for any signs of bleeding or hematoma, apply pressure if necessary, and report any abnormalities to the physician immediately.

Choice b reason:
Cardiac dysrhythmias may occur due to irritation of the heart muscle by the catheter during insertion. Monitoring the client's heart rhythm is essential to detect any new onset of arrhythmias, which could indicate complications from the procedure.

Choice c reason:
Electrolyte imbalances can result from the contrast dye used during a cardiac angiogram. The dye can affect kidney function, leading to changes in electrolyte levels. Monitoring electrolyte levels is important to prevent complications such as arrhythmias or fluid imbalances.

Choice d reason:
While discomfort at the catheter insertion site is expected, it is typically mild. However, the nurse should assess for discomfort as it may indicate other issues such as infection, bleeding, or a reaction to the procedure.
