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. A 4-year-old with acute lymphocytic leukemia (ALL) is receiving a chemotherapy protocol that includes methotrexate, an antimetabolite. Which information should the nurse provide the parents about caring for their child?

• A. Use sunblock or protective clothing when outdoors.
• B. Include the child in regular outings with the family.
• C. Obtain any childhood vaccinations that are not up-to-date.
• D. Use diluted commercial mouthwash for mouth care.

Correct answer: A

Rationale: The correct answer is to use sunblock or protective clothing when outdoors. Methotrexate can cause photosensitivity, making the child more prone to sunburns and skin damage. Therefore, advising the parents to protect their child's skin from direct sunlight exposure is crucial. Choice B is incorrect because exposing the child to direct sunlight without protection can worsen the photosensitivity caused by methotrexate. Choice C is incorrect as obtaining vaccinations is generally avoided during chemotherapy due to the child's compromised immune system. Choice D is incorrect as commercial mouthwash may contain alcohol, which can be irritating to the child's oral mucosa, especially during chemotherapy.

3. A client with a diagnosis of depression is prescribed an SSRI. What is the most important information the nurse should provide?

• A. Take the medication as prescribed.
• B. Avoid consuming grapefruit juice.
• C. Report any thoughts of self-harm immediately.
• D. Understand that improvement may take weeks.

Correct answer: C

Rationale: The most important information the nurse should provide to a client prescribed an SSRI for depression is to report any thoughts of self-harm immediately. SSRIs can increase suicidal ideation, especially at the beginning of treatment, so it is crucial to monitor for this and take appropriate actions. While it is important to take the medication as prescribed (Choice A), the immediate need for reporting self-harm ideation takes precedence. Avoiding grapefruit juice (Choice B) is a general precaution with certain medications but not as critical in this scenario. Understanding that improvement may take weeks (Choice D) is important for managing treatment expectations, but ensuring the client's safety in the context of suicidal ideation is the top priority.

4. A client with a diagnosis of heart failure is receiving furosemide (Lasix). Which electrolyte imbalance should the nurse monitor for?

• A. Hyperkalemia.
• B. Hyponatremia.
• C. Hypocalcemia.
• D. Hypokalemia.

Correct answer: D

Rationale: The correct answer is D: Hypokalemia. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Therefore, the nurse should monitor the client for low potassium levels. Choice A, Hyperkalemia, is incorrect as furosemide does not typically cause high potassium levels. Choice B, Hyponatremia, is incorrect as furosemide primarily affects potassium levels, not sodium. Choice C, Hypocalcemia, is incorrect as furosemide does not directly impact calcium levels.

5. A nurse in a pediatric unit is preparing to administer medication to a child. What should the nurse do to ensure the correct dosage?

• A. Check the child's weight
• B. Verify the medication order with a pharmacist
• C. Consult the child's parents
• D. Double-check the dosage calculations with another nurse

Correct answer: D

Rationale: When administering medication to children, it is crucial to ensure the correct dosage to prevent dosing errors. Double-checking the dosage calculations with another nurse can help verify the accuracy of the prescribed dose, reducing the risk of medication errors. While checking the child's weight (Choice A) is important for dosage calculation, it alone may not ensure the correctness of the dosage. Verifying the medication order with a pharmacist (Choice B) is essential, but it may not directly address the accuracy of dosage calculations. Consulting the child's parents (Choice C) is not a standard practice for verifying medication dosages and should not be solely relied upon for ensuring the correct dosage.
