Nursing Elites

1. A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

• A. Intercostal retractions
• B. Kussmaul respirations
• C. Low oxygen saturation (SpO2)
• D. Decreased venous O2 pressure

Correct answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.

2. When asked to describe in layman's terms an overview of the condition called osteomyelitis, what would be the nurse's best response?

• A. Osteomyelitis is a gradual breakdown and weakening of your bones. It's most often age-related.
• B. Osteomyelitis is caused by not having enough Vitamin D, which in turn causes your bones to be softer and demineralized.
• C. Osteomyelitis is an infection in the bone. It can be caused by bacteria reaching your bone from outside or inside your body.
• D. This is a question that should be directed to your healthcare provider.

Correct answer: C

Rationale: Osteomyelitis is an infection in the bone that can be caused by bacteria reaching the bone either from outside the body (such as through an open fracture) or inside the body (such as through the bloodstream). This response provides a concise and accurate explanation of osteomyelitis, making it the best choice. Choices A and B provide inaccurate information about the condition, attributing it to age-related bone breakdown and Vitamin D deficiency, which are not correct causes of osteomyelitis. Choice D deflects the question instead of providing the patient with a clear explanation, making it an inappropriate response.

3. Which response by the nurse best explains the purpose of ranitidine (Zantac) for a patient admitted with bleeding esophageal varices?

• A. The medication will reduce the risk of aspiration.
• B. The medication will inhibit the development of gastric ulcers.
• C. The medication will prevent irritation of the enlarged veins.
• D. The medication will decrease nausea and improve appetite.

Correct answer: C

Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.

4. What action will the nurse plan to take for a 40-year-old patient with multiple sclerosis (MS) who has urinary retention caused by a flaccid bladder?

• A. Decrease the patient's evening fluid intake.
• B. Teach the patient how to use the Cred method.
• C. Suggest the use of adult incontinence briefs for nighttime only.
• D. Assist the patient to the commode every 2 hours during the day.

Correct answer: B

Rationale: For a 40-year-old patient with multiple sclerosis experiencing urinary retention due to a flaccid bladder, teaching the Cred method is the appropriate action. The Cred method involves applying manual pressure over the bladder to aid in bladder emptying. Decreasing fluid intake is not the correct approach as it will not address the underlying issue of bladder emptying and may lead to dehydration and urinary tract infections. Using adult incontinence briefs only addresses the symptom of incontinence without addressing the bladder emptying problem. Assisting the patient to the commode every 2 hours does not actively address the issue of improving bladder emptying as effectively as teaching the Cred method.

5. A client complained of nausea, a metallic taste in her mouth, and fine hand tremors 2 hours after her first dose of lithium carbonate (Lithane). What is the nurse's best explanation of these findings?

• A. These side effects are common and should subside in a few days.
• B. The client is probably having an allergic reaction and should discontinue the drug.
• C. Taking the lithium on an empty stomach should decrease these symptoms.
• D. Decreasing dietary intake of sodium and fluids should minimize the side effects.

Correct answer: A

Rationale: The correct answer is, 'These side effects are common and should subside in a few days.' Nausea, metallic taste, and fine hand tremors are common side effects of lithium carbonate (Lithane) and typically diminish within a few days as the body adjusts to the medication. Option B is incorrect because these symptoms are not indicative of an allergic reaction. Option C is incorrect as taking lithium on an empty stomach does not directly address or decrease these specific side effects. Option D is also incorrect as reducing sodium and fluid intake is not the recommended approach to managing these particular side effects of lithium.
