Introduction to Community Health Nursing Questions
Question 1 of 5
While the client has a pulse oximeter on his fingertip, the nurse notices that sunlight is shining on the area of the sensor. The nurse’s action should be:
Correct Answer: C
Rationale: The correct answer is C: Cover the fingertip sensor with a towel or bedsheet. Sunlight shining on the sensor can interfere with accurate readings. By covering the sensor, the nurse eliminates the external light source and ensures correct measurements. Choice A is incorrect because sunlight can affect the accuracy of the pulse oximeter readings. Choice B is incorrect because changing the sensor location every 4 hours does not address the immediate issue of sunlight interference. Choice D is incorrect as setting the alarm does not solve the problem of sunlight affecting the sensor's accuracy.
Question 2 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 3 of 5
To obtain a specimen for a stool culture, the nurse should:
Correct Answer: C
Rationale: The correct answer is C because using tongue blades to transfer the stool into the container minimizes the risk of contamination. Placing a large stool directly into the container (A) may introduce contaminants. Using a dry container (B) may not preserve the specimen adequately. Dipping a rectal swab into the stool and placing it into a sterile test tube (D) may not provide enough sample for culture.
Question 4 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 5 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.
