1. When teaching the guardian of a 12-year-old male client about manifestations of puberty, which of the following physical changes typically occurs first?
- A. Appearance of downy hair on the upper lip
- B. Hair growth in the axillae
- C. Enlargement of the testes and scrotum
- D. Deepening of the voice
Correct answer: C
Rationale: During puberty in males, the first physical change that typically occurs is the enlargement of the testes and scrotum. This change is due to increased production of testosterone, which stimulates growth and development of the genital organs. The appearance of downy hair on the upper lip (Choice A) and hair growth in the axillae (Choice B) usually follow the enlargement of the testes and scrotum. Deepening of the voice (Choice D) is a later stage change that occurs during puberty as the larynx (voice box) grows and the vocal cords lengthen and thicken.
2. A healthcare professional is measuring vital signs for a client and notices an irregularity in the pulse. Which of the following actions should the healthcare professional take?
- A. Count the apical pulse rate for 1 full minute, and describe the rhythm in the chart.
- B. Recheck the pulse at the same site after 5 minutes.
- C. Measure the client’s blood pressure.
- D. Record the irregularity and continue with other vital signs.
Correct answer: A
Rationale: When an irregular pulse is detected, it is essential to count the apical pulse rate for a full minute to accurately determine the rhythm. This ensures a comprehensive assessment and helps in identifying any potential issues or abnormalities. Rechecking the pulse at the same site after 5 minutes (Choice B) may not provide an immediate understanding of the irregularity. Measuring the client's blood pressure (Choice C) is important but not directly related to addressing the irregular pulse. Recording the irregularity and continuing with other vital signs (Choice D) may overlook a potentially serious cardiac issue that requires immediate attention.
3. A client with diabetes mellitus is learning to self-administer insulin. Which action by the client indicates the need for further teaching?
- A. The client rotates injection sites on the abdomen.
- B. The client draws up the insulin dose after warming the vial to room temperature.
- C. The client pinches the skin before injecting the insulin.
- D. The client injects the insulin at a 90-degree angle.
Correct answer: B
Rationale: Drawing up insulin after warming the vial to room temperature indicates a need for further teaching, as insulin should be at room temperature for administration. Choice A is correct as rotating injection sites helps prevent lipodystrophy. Choice C is correct as pinching the skin helps ensure proper subcutaneous injection. Choice D is correct as injecting insulin at a 90-degree angle is the recommended technique for subcutaneous injections.
4. Which task can the RN delegate to an unlicensed assistive personnel (UAP)?
- A. Take a history on a newly admitted client
- B. Adjust the rate of a gastric tube feeding
- C. Check the blood pressure of a 2-hour postoperative client
- D. Check on a client receiving chemotherapy
Correct answer: C
Rationale: The correct answer is C. Checking the blood pressure of a 2-hour postoperative client is a task that can be safely delegated to an unlicensed assistive personnel (UAP) as it falls within their scope of practice. This task is routine and does not require specialized nursing knowledge or critical decision-making. Options A, B, and D involve tasks that require a higher level of training and critical thinking beyond the scope of a UAP. Taking a history, adjusting tube feeding rates, and monitoring a client receiving chemotherapy are responsibilities that should be performed by licensed healthcare providers who have the necessary skills and training.
5. While suctioning a client's nasopharynx, the nurse observes that the client's oxygen saturation remains at 94%, which is the same reading obtained prior to starting the procedure. What action should the nurse take in response to this finding?
- A. Complete the intermittent suction of the nasopharynx.
- B. Reposition the pulse oximeter clip to obtain a new reading.
- C. Stop suctioning until the pulse oximeter reading is above 95%.
- D. Apply an oxygen mask over the client's nose and mouth.
Correct answer: A
Rationale: The correct action for the nurse to take in this situation is to complete the intermittent suction of the nasopharynx. Since the oxygen saturation remains stable at 94%, which was the initial reading, it indicates that the procedure is not causing a significant drop in oxygen levels. Stopping the suctioning or applying oxygen may not be necessary as the saturation level is within an acceptable range. Repositioning the pulse oximeter clip is unlikely to change the reading significantly. Therefore, completing the procedure maintains care consistency and effectiveness, ensuring proper airway management without unnecessary interventions. Choices B, C, and D are incorrect because repositioning the pulse oximeter clip, stopping suctioning until a higher reading is achieved, and applying oxygen are not warranted based on the stable oxygen saturation level of 94% throughout the procedure.
