Nursing Elites

1. When using a metered-dose inhaler (MDI), which step is most important for ensuring effective medication delivery?

• A. Exhale completely before using the inhaler
• B. Inhale quickly while pressing down on the inhaler
• C. Shake the inhaler for 10 seconds before use
• D. Hold breath for 5 seconds after inhaling

Correct answer: A

Rationale: The correct step to ensure effective medication delivery when using a metered-dose inhaler (MDI) is to exhale completely before using the inhaler. This action helps create more space in the lungs for the medication to reach deeply into the airways. Inhaling quickly while pressing down on the inhaler (Choice B) may cause the medication to impact the throat rather than reaching the lungs. Shaking the inhaler for 10 seconds before use (Choice C) is important to mix the medication but not the most crucial step for effective delivery. While holding the breath for 5 seconds after inhaling (Choice D) can help the medication stay in the lungs momentarily, exhaling completely before inhalation is more critical for optimal drug deposition.

2. The client with diabetes is being taught about the importance of foot care. Which statement by the client indicates a need for further teaching?

• A. ''I will inspect my feet daily for any cuts or blisters.''
• B. ''I will soak my feet in warm water every day.''
• C. ''I will wear shoes that fit properly to avoid injury.''
• D. ''I will avoid walking barefoot to protect my feet.''

Correct answer: B

Rationale: Choice B is the correct answer because soaking feet daily can lead to skin breakdown, making it inappropriate for clients with diabetes. Inspecting feet daily for cuts or blisters (Choice A), wearing properly fitting shoes (Choice C), and avoiding walking barefoot (Choice D) are all appropriate measures to maintain foot health for clients with diabetes.

3. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?

• A. Serum glucose of 180 mg/dL
• B. Blood pH of 7.30
• C. Positive urine ketones
• D. Serum bicarbonate of 25 mEq/L

Correct answer: C

Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.

4. A client with a history of chronic back pain is prescribed oxycodone for pain management. What is the most important instruction the nurse should provide?

• A. Take the medication with food to reduce stomach upset
• B. Avoid operating heavy machinery while taking this medication
• C. Increase physical activity to enhance pain relief
• D. Report any signs of respiratory depression immediately

Correct answer: D

Rationale: The correct answer is D: 'Report any signs of respiratory depression immediately.' Respiratory depression is a severe side effect of opioids like oxycodone and can be life-threatening. It is crucial for the nurse to instruct the client to report any signs such as slow or shallow breathing, difficulty breathing, or confusion. Choice A is incorrect as taking oxycodone with or without food does not significantly affect its efficacy. Choice B is incorrect because avoiding driving is important due to the potential impairment caused by oxycodone, but reporting respiratory depression is more critical. Choice C is incorrect as increasing physical activity may not always be suitable for individuals with chronic back pain and is not directly related to preventing respiratory depression.

5. When teaching a diabetic client about foot care, what information is most important?

• A. Inspect feet daily
• B. Wear cotton socks
• C. Use lukewarm water to wash feet
• D. Cut nails straight across

Correct answer: A

Rationale: Inspecting feet daily is crucial for diabetic clients as it can help prevent complications like infections and ulcers. This practice allows for early detection of any foot issues, enabling timely intervention. While wearing cotton socks (choice B) is beneficial as they absorb moisture and reduce the risk of fungal infections, it is not as critical as daily foot inspection. Using lukewarm water to wash feet (choice C) is important to prevent burns or skin damage in diabetic clients with decreased sensation, but it is not as crucial as daily foot inspection. Cutting nails straight across (choice D) is essential to prevent ingrown nails, but it is not the most important information when educating diabetic clients about foot care.
