An adult client is admitted with AIDS and oral candidiasis manifested by several painful mouth ulcers. The nurse delegates oral care to the unlicensed assistive personnel (UAP) and discusses how to assist the client. Which instruction should the nurse provide the UAP?

Choice A reason: A heart rate of 120 beats/minute requires immediate intervention, as albuterol, a beta-agonist, stimulates cardiac beta-1 receptors, causing tachycardia. In emphysema, repeated dosing increases cardiovascular stress, risking arrhythmias or ischemia, necessitating evaluation to adjust therapy or address potential overdose effects.

Choice B reason: Respiratory rate of 28 breaths/minute is elevated but expected in emphysema with dyspnea. Albuterol aims to reduce bronchospasm, and this rate does not indicate immediate danger compared to tachycardia, which poses a cardiovascular risk, making it less urgent.

Choice C reason: Oxygen saturation of 90% is low but common in emphysema exacerbations. Albuterol improves airflow, and supplemental oxygen may address hypoxia. While concerning, this is less immediately life-threatening than tachycardia, which indicates potential albuterol toxicity, requiring urgent intervention.

Choice D reason: Peak expiratory flow at 60% reflects airflow limitation in emphysema, improved by albuterol. While low, it is not as urgent as tachycardia, which signals cardiovascular strain from repeated albuterol doses, posing a greater immediate risk to the client’s stability.

Choice A reason: Hemoglobin is critical to review, as diclofenac, an NSAID, can cause gastrointestinal bleeding, leading to anemia. Pale appearance and fatigue suggest blood loss, reducing oxygen-carrying capacity. Low hemoglobin confirms anemia, necessitating intervention to prevent further complications, making this the priority laboratory value.

Choice B reason: Serum creatinine monitors renal function, as diclofenac may cause nephrotoxicity, but pale appearance and fatigue point to anemia from bleeding, not renal issues. Renal effects are less immediate than blood loss, making hemoglobin more urgent to assess in this context.

Choice C reason: Blood glucose is irrelevant, as diclofenac does not significantly affect glucose metabolism. Pale appearance and fatigue are classic anemia symptoms, not hypoglycemia, making hemoglobin the priority over glucose, which does not explain the client’s presentation in rheumatoid arthritis.

Choice D reason: Liver enzymes monitor hepatotoxicity, a diclofenac side effect, but pale appearance and fatigue suggest anemia from gastrointestinal bleeding, not liver dysfunction. Hemoglobin directly addresses the likely cause, making it more critical than liver enzymes for immediate evaluation.
