During an assessment of an anxious client diagnosed with right lower lobe pneumonia, the nurse notes a new onset change in mental status and tachypnea. The latest vital signs for the client are T: 98.4 F; HR: 108; RR: 28; BP: 144/90; Pulse ox: 88%. What is the priority nursing action?

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
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.
