1. Why should a palpated pressure be performed before auscultating blood pressure?

• A. To more clearly hear the Korotkoff sounds.
• B. To detect the presence of an auscultatory gap.
• C. To avoid missing a falsely elevated blood pressure.
• D. To more readily identify phase IV of the Korotkoff sounds.

Correct answer: B

Rationale: Performing a palpated pressure before auscultating blood pressure helps in detecting the presence of an auscultatory gap. An auscultatory gap is a period during blood pressure measurement when Korotkoff sounds temporarily disappear before reappearing. Inflation of the cuff 20 to 30 mm Hg beyond the point where a palpated pulse disappears helps in identifying this gap. This technique ensures accurate blood pressure measurement by preventing the underestimation of blood pressure values. The other options are incorrect because palpating the pressure is not primarily done to hear Korotkoff sounds more clearly, avoid missing falsely elevated blood pressure, or readily identify a specific phase of Korotkoff sounds.

2. Which of these statements is true regarding the use of Standard Precautions in the healthcare setting?

• A. Standard Precautions apply to all body fluids, except sweat.
• B. Alcohol-based hand rub should be used if hands are not visibly dirty.
• C. Standard Precautions are intended for use with all patients, regardless of their risk or presumed infection status.
• D. Standard Precautions are to be used only when non-intact skin, excretions containing visible blood, or expected contact with mucous membranes are present.

Correct answer: C

Rationale: Standard Precautions are designed to reduce the risk for transmission of microorganisms from both recognized and unrecognized sources. They are intended for use with all patients, regardless of their risk or presumed infection status. Standard Precautions apply to all body fluids, secretions, and excretions except sweat - whether or not they contain visible blood, non-intact skin, or mucous membranes. Hands should be washed with soap and water if visibly soiled with blood or body fluids. Alcohol-based hand rubs can be used if hands are not visibly soiled. Choice A is incorrect because Standard Precautions apply to all body fluids, secretions, and excretions except sweat. Choice B is incorrect because alcohol-based hand rub should be used when hands are not visibly dirty. Choice D is incorrect because Standard Precautions are not limited to situations involving non-intact skin, excretions with visible blood, or expected mucous membrane contact.

3. A client is being instructed on how to use crutches. Which of the following information should be included in the teaching?

• A. Place the majority of body weight on the axilla.
• B. Dry crutch tips with a paper towel if they become wet.
• C. Use the crutches for support to lift both feet simultaneously when ascending stairs.
• D. Both B and C.

Correct answer: B

Rationale: When instructing a client on how to use crutches for ambulation, it is important to emphasize keeping the crutch tips dry to prevent slipping while bearing weight on them. Moisture on the crutch tips can lead to accidents. Therefore, the correct answer is to dry the crutch tips with a paper towel if they become wet. Choice A, placing the majority of body weight on the axilla, is incorrect as the weight should be borne through the hands, not the axilla, to avoid nerve damage. Choice C, using the crutches to lift both feet simultaneously when ascending stairs, is incorrect as the client should ascend stairs by placing weight on the unaffected leg first, followed by the crutches and then the affected leg. This method provides stability and safety during stair climbing.

4. During an assessment, the nurse notices that a patient is handling a small charm that is tied to a leather strip around their neck. Which action by the nurse is appropriate?

• A. Ask the patient about the item and its significance.
• B. Ask the patient to lock the item with other valuables in the hospital's safe.
• C. Tell the patient that a family member should take valuables home.
• D. No action is necessary.

Correct answer: A

Rationale: The small charm tied to a leather strip is likely an amulet, which many cultures consider an important means of protection from 'evil spirits.' When a patient appears to have a health practice the nurse is unfamiliar with, the nurse should ask for clarification in a non-judgmental way that communicates acceptance of their beliefs and allows for open communication. Thus, the nurse in this situation should inquire about the amulet's meaning to the patient. Asking the patient to lock the item with other valuables in the hospital's safe, telling the patient that a family member should take valuables home, or doing nothing does not address the importance or meaning of a cultural health practice to the patient and does not allow the nurse to gain an understanding of the patient's cultural health practices.

5. A patient's blood pressure is 118/82 mm Hg. The patient asks the nurse, "What do the numbers mean?"? Which is the best reply by the nurse?

• A. "The numbers are within the normal range and are nothing to worry about."?
• B. "The bottom number is the diastolic pressure and reflects the pressure in the arteries when the heart relaxes."?
• C. "The top number is the systolic blood pressure and reflects the pressure of the blood against the arteries when the heart contracts."?
• D. "The concept of blood pressure can be complex. The primary thing to be concerned about is the top number, or the systolic blood pressure."?

Correct answer: C

Rationale: The systolic pressure is the maximum pressure felt on the artery during left ventricular contraction, or systole. The diastolic pressure is the elastic recoil, or resting, pressure that the blood constantly exerts in between each contraction. The nurse should answer the patient's question in terms they can understand and not just say it is normal and there is nothing to worry about. The diastolic pressure is the pressure in the vessels when the heart is at rest, not the stroke volume. Both the systolic and diastolic blood pressure are important. Choice A is incorrect as providing a vague reassurance does not address the patient's query. Choice B is incorrect as it inaccurately describes the diastolic pressure as reflecting stroke volume, which is incorrect. Choice D is incorrect as it oversimplifies the explanation, focusing solely on the top number without providing a complete understanding of blood pressure.
