1. The supervising RN asks you to bring the unit's collected lab specimens to the lab 'stat'. You should ______________.
- A. not decline this task because nurses do not handle 'stats'.
- B. run this errand as promptly as possible
- C. run this errand immediately and without delay
- D. Complete this task before the end of your shift or after your lunch.
Correct answer: C
Rationale: In healthcare settings, 'stat' is commonly used to indicate that something should be done immediately and without any delay. It is a critical term used to prioritize urgent tasks. Nurses are responsible for various tasks, including handling urgent requests such as transporting lab specimens promptly. Option A is incorrect as nurses can handle urgent tasks like 'stats'. Option B is not as specific as option C, which clearly emphasizes the need for immediate action. Option D is incorrect as it suggests delaying the task until later, which goes against the urgency implied by the term 'stat'.
2. What does preload refer to?
- A. The volume of blood entering the left side of the heart
- B. The volume of blood entering the right side of the heart
- C. The pressure in the venous system that the heart must overcome to pump the blood
- D. The pressure in the arterial system that the heart must overcome to pump the blood
Correct answer: B
Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.
3. When cleansing the genital area during perineal care, the nurse should _____________.
- A. cleanse the penis with a circular motion starting from the base and moving toward the tip.
- B. replace the foreskin after it has been pushed back to cleanse an uncircumcised penis.
- C. cleanse the rectal area first and then clean the patient's genital area.
- D. use the same area on the washcloth for each washing and rinsing stroke for a female resident.
Correct answer: B
Rationale: During perineal care, when cleansing the genital area of an uncircumcised male patient, it is crucial to retract the foreskin to clean the area underneath. This helps in the removal of smegma, a substance that can accumulate and lead to bacterial growth and infection if not cleaned properly. The foreskin should then be replaced back to its original position after cleaning to ensure proper hygiene and prevent any potential complications. Choices A, C, and D are incorrect because they do not address the specific care required for an uncircumcised penis, which involves retracting and replacing the foreskin.
4. A nursing care plan states, 'Assist the patient to the bedside commode PRN.' When will this patient get this assistance to the commode?
- A. Whenever needed
- B. At bedtime
- C. During the night
- D. During the day
Correct answer: A
Rationale: The correct answer is 'Whenever needed.' The abbreviation 'PRN' stands for 'pro re nata,' which translates to 'as needed' or 'whenever necessary.' This means that the patient will receive assistance to the commode whenever they require it, based on their individual needs and condition. Choices B, C, and D are incorrect because 'PRN' does not specify a specific time like bedtime, during the night, or during the day; instead, it indicates assistance based on the patient's needs.
5. A client is about to have a TENS unit attached for pain relief. Which of the following actions is most appropriate in this situation?
- A. Inform the client that he may experience tingling sensations.
- B. Connect the TENS unit before the client goes to bed for the night.
- C. Inform the client that the TENS unit may have pain-reducing effects for 10 to 15 days.
- D. After treatment, inform the client that he may not use a TENS unit again for at least 2 weeks.
Correct answer: A
Rationale: When attaching a TENS unit for pain relief, it is essential to inform the client that he may experience tingling sensations. This is a common sensation experienced when using a TENS unit, but it should not cause muscle twitching. The therapeutic effects of a TENS unit usually last between 3 to 5 days. Choice B is incorrect because there is no specific recommendation to connect the TENS unit before bedtime. Choice C is incorrect as stating that the TENS unit may have pain-reducing effects for 10 to 15 days is inaccurate, as the effects typically last 3 to 5 days. Choice D is incorrect because there is no guideline suggesting that the client cannot use a TENS unit again for at least 2 weeks after treatment.
