Introduction to Professional Nursing Questions
Question 1 of 5
The nurse attached a pulse oximeter to a client. She knows that the purpose of this is to:
Correct Answer: C
Rationale: Rationale: Choice C is correct because a pulse oximeter measures oxygen saturation in arterial blood, providing crucial information on the client's oxygen levels. This helps monitor respiratory status and determine the need for supplemental oxygen. Choice A is incorrect as tissue perfusion is not directly assessed by a pulse oximeter. Choice B is incorrect as it measures hemoglobin indirectly. Choice D is incorrect as anti-hypertensive medications do not impact oxygen saturation directly.
Question 2 of 5
If all of the following nursing measures are possible, which helps most when planning to obtain a sputum specimen?
Correct Answer: A
Rationale: The correct answer is A: Provide the client with generous fluid intake. Adequate fluid intake helps in thinning respiratory secretions, making it easier to obtain a sputum specimen. This measure promotes hydration, which can facilitate coughing and sputum production. Regular position changes (B) may help prevent complications like pressure ulcers but are not directly related to obtaining a sputum specimen. A high-protein diet (C) and sufficient rest periods (D) are important for overall client well-being but do not specifically aid in obtaining a sputum specimen.
Question 3 of 5
To prepare a patient for a thoracentesis, the nurse should:
Correct Answer: B
Rationale: The correct answer is B: Ask the patient to sign a consent form for the procedure. This step is crucial to ensure that the patient understands the risks and benefits of the thoracentesis procedure and gives informed consent. Signing a consent form also protects both the patient and the healthcare provider legally. A: Reminding the patient to eat or drink nothing for six hours before the procedure is not necessary for a thoracentesis, as it is not typically a procedure that requires fasting. C: Positioning the patient on the side of the bed leaning over the bedside table is not correct for a thoracentesis procedure. The patient should be sitting upright or slightly leaning forward to facilitate the procedure. D: Pulling the privacy curtain and dimming the lights of the room are not essential steps for preparing a patient for a thoracentesis. These actions are more related to creating a comfortable and private environment but are not directly related to the procedure itself.
Question 4 of 5
The physician orders ampicillin (Omnipen), 500 mg by mouth every 6 hours. This medication order is an example of:
Correct Answer: A
Rationale: The correct answer is A: A standard written order. This is because a standard written order specifies the medication, dose, route, frequency, and duration of administration. In this case, the order for ampicillin 500 mg by mouth every 6 hours is clearly outlined and does not specify any special circumstances like a one-time dose or immediate administration (stat order). Additionally, it is not an as-needed order which would only be given based on the patient's symptoms or condition. It also does not qualify as a single order as it is intended to be administered multiple times at specified intervals.
Question 5 of 5
The nurse is setting an infusion pump to deliver 4 mcg/kg/min of a medication to a patient who weighs 50 kg. How many micrograms should the patient receive in one hour?
Correct Answer: C
Rationale: To determine the correct answer, we first calculate the total micrograms the patient should receive in one hour. 1. Multiply the patient's weight (50 kg) by the infusion rate (4 mcg/kg/min) to get the total micrograms/min: 50 kg * 4 mcg/kg/min = 200 mcg/min. 2. To find the total micrograms in one hour, multiply the micrograms/min by 60 minutes: 200 mcg/min * 60 min = 12000 mcg. Therefore, the patient should receive 12,000 micrograms in one hour, making choice C the correct answer. Explanation for incorrect choices: A: 200 - This is the total micrograms per minute, not for the whole hour. B: 1200 - This is close to the correct answer, but it doesn't account for the full hour. D: 0 - This is incorrect as the patient should receive medication over the hour.
