Introduction to Community Health Nursing Questions
Question 1 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 2 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 3 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 4 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.
Question 5 of 5
The nurse understands that a diabetic patient should have which of the following tests performed to determine the effect of therapy?
Correct Answer: B
Rationale: The correct answer is B: Hemoglobin A1C. This test reflects average blood sugar levels over the past 2-3 months, providing a long-term view of diabetes management effectiveness. A is incorrect as it assesses different blood components. C is important but not specific to diabetes therapy monitoring. D is a nonspecific marker for inflammation, not directly related to diabetes control.
