Nursing Elites

1. What most influences the severity of respiratory distress syndrome (RDS)?

• A. Poor cough and gag reflex
• B. The gestational age at birth
• C. Administering high concentrations of oxygen
• D. The sex of the infant

Correct answer: B

Rationale: The correct answer is B. The gestational age at birth most influences the severity of respiratory distress syndrome (RDS). RDS is caused by a deficiency of surfactant and it occurs almost exclusively in preterm, low-birth weight infants. Therefore, the gestational age at birth is a key factor in determining the likelihood and severity of RDS. Choices A, C, and D are incorrect as they do not directly relate to the primary factor influencing the severity of RDS.

2. The health care provider is treating a child with meningitis with a course of antibiotic therapy. When should the nurse expect the child to be out of isolation?

• A. When the course of antibiotics is complete
• B. When a negative CNS culture is obtained
• C. When the antibiotics have been initiated for 24 hours
• D. When the child has no symptoms of the disease

Correct answer: C

Rationale: The correct answer is C because a child with bacterial meningitis should be isolated for at least 24 hours until antibiotic therapy has been initiated. This period allows the antibiotics to start working against the infection, reducing the risk of spreading it to others. Choice A is incorrect because isolation is not solely based on completing the course of antibiotics; the initiation is crucial. Choice B is incorrect as waiting for a negative CNS culture may take longer and delay necessary precautions. Choice D is incorrect as symptom resolution does not guarantee the eradication of the infection and may still pose a risk of transmission.

3. The nurse assesses an adult male client 24 hours following abdominal surgery and finds that his blood pressure is 98/40 mm Hg, he is tachycardic, restless, and irritable. Which action should the nurse take first?

• A. Notify the healthcare provider of the findings.
• B. Ensure that the IV is infusing at the prescribed rate.
• C. Listen to lung sounds.
• D. Check under his back for evidence of bleeding.

Correct answer: D

Rationale: In this scenario, the nurse should first check under the client for evidence of bleeding. A blood pressure of 98/40 mm Hg, along with tachycardia, restlessness, and irritability, could indicate internal hemorrhage following abdominal surgery. Checking for bleeding under the back is crucial to rule out this life-threatening complication. Notifying the healthcare provider, ensuring IV infusion, or listening to lung sounds can be important but are secondary to ruling out immediate life-threatening conditions like internal bleeding.

4. The nurse is teaching a client how to collect a sputum specimen. Which steps should the nurse instruct the client to follow when collecting sputum?

• A. Breathe deeply, followed by swallowing.
• B. Breathe deeply, followed by spitting into a cup.
• C. Breathe deeply, followed by coughing up the sputum.
• D. Breathe deeply, followed by clearing the throat.

Correct answer: C

Rationale: The correct answer is to instruct the client to breathe deeply followed by coughing up the sputum. This method ensures that the specimen is collected from the lower respiratory tract and is not contaminated by saliva. Choice A (swallowing) does not result in sputum collection, while choice B (spitting into a cup) may lead to saliva contamination. Choice D (clearing the throat) is not an effective way to collect sputum as it may involve getting rid of saliva, not sputum.

5. A client with deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin?

• A. Complete blood count (CBC)
• B. Activated partial thromboplastin time (aPTT)
• C. Prothrombin time (PT)
• D. International normalized ratio (INR)

Correct answer: B

Rationale: The correct answer is B: Activated partial thromboplastin time (aPTT). This test is used to monitor the effectiveness of heparin therapy. A complete blood count (CBC) (choice A) is not specific for monitoring heparin therapy. Prothrombin time (PT) (choice C) and International normalized ratio (INR) (choice D) are more commonly used to monitor warfarin therapy, not heparin.
