1. What type of blood pressure measurement error is most likely to occur if the nurse does not check for the presence of an auscultatory gap?

Correct answer: C

Rationale: If an auscultatory gap is undetected, a falsely low systolic reading may occur. This gap can lead to an underestimation of the systolic blood pressure, causing potential misinterpretation of the patient's condition. The diastolic blood pressure may not be heard due to the gap, but the critical issue in this scenario is the risk of underestimating systolic blood pressure, which can impact clinical decision-making. Choices B, C, and D are incorrect because the key concern in this context is the potential for a falsely low systolic blood pressure reading when an auscultatory gap is not assessed.

2. The abbreviation pc is defined as ________________.

Correct answer: C

Rationale: The correct answer is C: 'after the meal.' In medical terminology, 'pc' is an abbreviation for 'post cibum,' which means 'after eating' or 'after the meal.' This term is used to indicate when a medication should be taken concerning meals. Choices A, B, and D are incorrect. 'Before the meal' (A) is typically abbreviated as 'ac,' 'with the meal' (B) is abbreviated as 'pc,' and 'post corpi' (D) is not a valid medical abbreviation or term.

3. A client is about to have a TENS unit attached for pain relief. Which of the following actions is most appropriate in this situation?

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.

4. Which practice will help reduce the risk of a needlestick injury?

Correct answer: C

Rationale: To reduce the risk of a needlestick injury, it is essential to keep a sharps container nearby where it can be easily accessed. This practice ensures quick and safe disposal of needles after use, minimizing the chances of accidental needlesticks. Recapping needles should be avoided as it increases the risk of injuries. Passing needles between workers should also be avoided to prevent accidental needle pricks during handovers. Therefore, the best practice to prevent needlestick injuries is to maintain a sharps container nearby for safe and immediate disposal of needles.

5. When considering the structural organization of the human body, what is the basic unit of life?

Correct answer: D

Rationale: The basic unit of life is the cell. Cells are considered the fundamental unit of life because they are capable of carrying out all the processes necessary for life, such as growth, reproduction, responding to stimuli, and more. While chemicals, atoms, and molecules are essential components of cells and living organisms, they are not considered the basic unit of life. Chemicals are general substances, atoms are the smallest units of matter, and molecules are combinations of atoms. Therefore, the correct answer is cells, as they are the building blocks of all living organisms.
