Introduction to Community Health Nursing Questions
Question 1 of 5
If a client has been suctioned, how long should the nurse wait before drawing an arterial blood gas?
Correct Answer: D
Rationale: The correct answer is D (20 minutes) because after suctioning, it takes time for the respiratory system to stabilize and for arterial blood gas values to return to baseline. Waiting 20 minutes allows for accurate assessment of respiratory status. Choice A (5 minutes) is too soon and may lead to skewed results due to immediate changes post-suctioning. Choice B (10 minutes) is still too early for accurate results. Choice C (15 minutes) is closer but may not provide sufficient time for full recovery post-suctioning. Therefore, waiting for 20 minutes ensures more reliable arterial blood gas values.
Question 2 of 5
The medication order of a client indicates: hs. This means that the nurse should administer the medication:
Correct Answer: D
Rationale: The correct answer is D: At bedtime. Rationale: 1. "hs" stands for "hora somni," Latin for bedtime. 2. Administering medication at bedtime ensures it is effective during nighttime. 3. Other choices are incorrect: A is subjective, B is immediate, and C is before meals which contradicts the meaning of "hs."
Question 3 of 5
The nurse is to administer an IV infusion of a medication at 10 units/kg/hour. The patient weighs 50 kilograms. The medication concentration is 50,000 units per 1000 ml. The nurse should set the infusion rate at:
Correct Answer: A
Rationale: The correct answer is A (10 ml/hr). To calculate the infusion rate, first, determine the total dose required per hour (10 units/kg/hour x 50 kg = 500 units/hour). Then, convert the medication concentration to units per ml (50,000 units/1000 ml = 50 units/ml). Finally, divide the total dose required per hour by the medication concentration (500 units/hour ÷ 50 units/ml = 10 ml/hr). This ensures the patient receives the correct dosage per hour based on their weight and the medication concentration. Choices B, C, and D are incorrect as they do not follow the correct calculation method or do not take into account the patient's weight and medication concentration.
Question 4 of 5
For a client who has a chest tube connected to a closed water-seal drainage system, the nurse should include which action in the plan of care?
Correct Answer: A
Rationale: The correct answer is A: Measuring and documenting the drainage in the collection chamber. This is essential to monitor the client's condition and assess for any changes in drainage, which can indicate complications. Maintaining continuous bubbling in the water-seal chamber (B) is incorrect because it may indicate an air leak, which should be addressed. Keeping the collection chamber at chest level (C) is incorrect because it is not a critical action for the care of the chest tube. Removing the chest tube every hour (D) is incorrect and can lead to complications and is not a standard practice in chest tube management.
Question 5 of 5
Independent nursing interventions commonly used for clients with pressure ulcers include which of the following?
Correct Answer: A
Rationale: Rationale for Correct Answer (A): Changing the client's position regularly helps to minimize pressure on the ulcer site, promoting circulation and preventing further tissue damage. This intervention is essential for preventing pressure ulcers and promoting healing. Other Choices Incorrect: B: Applying a drying agent like antacid can be harmful as it may further dry out the tissue and impede healing. C: Debriding the ulcer is not an independent nursing intervention and should be performed by a healthcare provider to remove necrotic tissue safely. D: This choice does not provide a specific nursing intervention for pressure ulcers but rather states a general concept that necrotic tissue can impede healing.
