1. The healthcare provider attaches a pulse oximeter to a client's fingers and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?

• A. BP 142/88 mmHg
• B. 2+ edema of fingers and hands
• C. Radial pulse volume is +3
• D. Capillary refill time is 2 seconds

Correct answer: B

Rationale: Edema in the fingers and hands can impede the proper functioning of the pulse oximeter, leading to a falsely low oxygen saturation reading. Edema alters the transmission of light through the tissues, affecting the accuracy of the measurement. Therefore, the presence of edema in the fingers and hands is the most likely factor contributing to the low oxygen saturation reading of 91%.

2. Which action should the nurse implement when using the confrontation technique during a vision exam?

• A. Use an ophthalmoscope to observe the client's pupil constriction when a strong light is shone on it.
• B. Stand behind the client and direct the client to report when an object enters the peripheral field of vision.
• C. Display a series of four cards with printing of varying sizes to the client and ask which card the client sees most clearly.
• D. Sit facing the client, look directly at the client's face, and move an object inward from the periphery.

Correct answer: D

Rationale: During a vision exam, the confrontation technique is used to assess peripheral vision. By sitting facing the client and moving an object inward from the periphery while looking directly at the client's face, the nurse allows the client to indicate when the object enters the visual field. This method helps in determining the extent of the client's peripheral vision accurately. Choices A, B, and C are incorrect as they do not describe the appropriate method for using the confrontation technique during a vision exam. Choice A involves using an ophthalmoscope to observe pupil constriction, choice B involves testing the peripheral field of vision without the confrontation technique, and choice C describes the Snellen eye chart test for visual acuity, which is not related to the confrontation technique.

3. A client in a long-term care facility reports to the nurse that he has not had a bowel movement in 2 days. Which intervention should the nurse implement first?

• A. Instruct the caregiver to offer a glass of warm prune juice at mealtimes.
• B. Notify the healthcare provider and request a prescription for a large-volume enema.
• C. Assess the client's medical record to determine the client's normal bowel pattern.
• D. Instruct the caregiver to increase the client's fluids to five 8-ounce glasses per day.

Correct answer: C

Rationale: When a client reports a change in bowel habits, the first step for the nurse is to assess the client's normal bowel pattern by reviewing the medical records. This assessment helps the nurse understand the client's baseline, which is crucial before initiating any interventions. By determining the client's usual bowel habits, the nurse can identify deviations from the norm and make informed decisions on the appropriate course of action. Assessing the client's medical record is a critical first step in addressing the client's bowel concerns. Choices A, B, and D are incorrect because they jump to interventions without first establishing the client's normal bowel pattern. Offering warm prune juice, requesting a large-volume enema, or increasing fluids may not be appropriate until the nurse knows the client's regular bowel habits and can assess the situation effectively.

4. How many drops per minute should a client weighing 182 pounds receive if a nurse mixes 50 mg of Nipride in 250 ml of D5W and plans to administer the solution at a rate of 5 mcg/kg/min? The drip factor is 60 gtt/ml.

• A. 31 gtt/min.
• B. 62 gtt/min.
• C. 93 gtt/min.
• D. 124 gtt/min.

Correct answer: D

Rationale: To determine the drops per minute for the client, first convert the client's weight from pounds to kilograms: 182/2.2 = 82.73 kg. Calculate the dosage by multiplying 5 mcg by the client's weight in kg: 5 mcg/kg/min × 82.73 kg = 413.65 mcg/min. Find the concentration of the solution in mcg/ml by dividing 250 ml by 50,000 mcg (50 mg): 250 ml/50,000 mcg = 200 mcg/ml. As the client needs 413.65 mcg/min and the solution is 200 mcg/ml, the client should receive 2.07 ml per minute. Finally, using the drip factor of 60 gtt/ml, multiply the ml per minute by the drip factor: 60 gtt/ml × 2.07 ml/min = 124.28 gtt/min, which rounds to 124 gtt/min. Therefore, the client should receive 124 drops per minute. Choice D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate calculation based on the client's weight, dosage, concentration of the solution, and drip factor.

5. During the insertion of a nasogastric tube (NGT), the client begins to cough and gag. What action should the healthcare professional take?

• A. Stop advancing the tube and allow the client to rest
• B. Remove the tube and try again after a few minutes
• C. Continue inserting the tube while the client sips water
• D. Withdraw the tube slightly and pause before continuing

Correct answer: D

Rationale: When a client begins to cough and gag during the insertion of a nasogastric tube, withdrawing the tube slightly and pausing is the appropriate action. This technique helps prevent further irritation, gives the client a moment to recover, and allows for a smoother continuation of the insertion process. Choice A is incorrect because allowing the client to rest without adjusting the tube position might not address the issue. Choice B is incorrect as removing the tube without addressing the cause of coughing and gagging may lead to repeated discomfort. Choice C is incorrect as continuing to insert the tube while the client is experiencing difficulties can increase discomfort and potential complications.
