Nursing Elites

1. A nurse is teaching a client about the use of a metered-dose inhaler (MDI). Which instruction should the nurse include in the teaching?

• A. Inhale the medication deeply for 3-5 seconds
• B. Exhale forcefully before inhaling
• C. Shake the MDI vigorously before use
• D. Hold the mouthpiece 2.5-5 cm (1-2 in) in front of the mouth

Correct answer: A

Rationale: Corrected Rationale: Inhaling the medication deeply for 3-5 seconds and holding the breath for 10 seconds after inhalation ensures effective medication delivery to the lungs. Choice A is the correct instruction for the use of a metered-dose inhaler (MDI). Choice B, exhaling forcefully before inhaling, is incorrect as it can lead to decreased medication delivery. Choice C, shaking the MDI vigorously before use, is also incorrect as excessive shaking can cause the medication to clump. Choice D, holding the mouthpiece 2.5-5 cm (1-2 in) in front of the mouth, is not recommended as it may lead to improper inhalation technique.

2. A nurse is assessing a client who has diabetic ketoacidosis (DKA). Which of the following laboratory findings should the nurse expect?

• A. Blood glucose 120 mg/dL
• B. pH 7.32
• C. HCO3 25 mEq/L
• D. PaCO2 48 mm Hg

Correct answer: B

Rationale: The correct answer is B. A pH of 7.32 indicates metabolic acidosis, which is a hallmark of diabetic ketoacidosis (DKA). In DKA, blood glucose levels are typically elevated, bicarbonate levels are often low, and there is a compensatory respiratory response leading to a decrease in PaCO2. Option A is incorrect because a blood glucose level of 120 mg/dL is within the normal range and not indicative of DKA. Option C is incorrect because an HCO3 level of 25 mEq/L is not typically seen in DKA where bicarbonate levels are usually lower. Option D is incorrect because a PaCO2 of 48 mm Hg would not be expected in DKA; it would typically be lower due to compensatory respiratory alkalosis.

3. A healthcare professional is verifying nasogastric tube placement by the pH of aspirated gastric fluid. Which of the following pH values provides a good indication of correct tube placement?

• A. 2
• B. 5
• C. 7
• D. 9

Correct answer: A

Rationale: The correct answer is A: '2'. Gastric contents with a pH between 0 and 4 provide a good indication of appropriate tube placement. A pH of 2 is within this range, indicating that the tube is correctly placed in the stomach. Choices B, C, and D are incorrect because a pH of 5, 7, or 9 does not fall within the expected acidic pH range of gastric fluid.

4. A healthcare professional is preparing to administer a dose of naloxone. Which of the following should the healthcare professional assess?

• A. Heart rate
• B. Respiratory rate
• C. Blood pressure
• D. Temperature

Correct answer: B

Rationale: Correct. Naloxone is used to reverse opioid overdose, which can cause respiratory depression. Assessing the respiratory rate before administering naloxone is crucial to monitor the patient's breathing. Choices A, C, and D are important assessments in general patient care but are not specifically crucial before administering naloxone for opioid overdose.

5. A nurse is caring for a client with Alzheimer’s disease. Which action should the nurse include in the plan of care to support the client’s cognitive function?

• A. Place a daily calendar in the kitchen
• B. Replace buttoned clothing with zippered items
• C. Replace the carpet with hardwood floors
• D. Create variation in the daily routine

Correct answer: A

Rationale: Placing a daily calendar in the kitchen is essential to help clients with Alzheimer's stay oriented to time and maintain cognitive function. It supports their ability to recall the day, date, and upcoming events, promoting a sense of control over their environment. Choices B, C, and D do not directly target cognitive function support in clients with Alzheimer's disease. While replacing buttoned clothing with zippered items may aid in dressing independently, changing the flooring or introducing variation in the daily routine does not specifically address cognitive function support.
