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?

• A. Diastolic blood pressure may not be heard.
• B. Diastolic blood pressure may be falsely low.
• C. Systolic blood pressure may be falsely low.
• D. Systolic blood pressure may be falsely high.

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. When considering the concepts related to blood pressure, which statement best describes the concept of mean arterial pressure (MAP)?

• A. MAP is the pressure of the arterial pulse.
• B. MAP reflects the stroke volume of the heart.
• C. MAP is the pressure forcing blood into the tissues, averaged over the cardiac cycle.
• D. MAP is an average of the systolic and diastolic blood pressures and reflects tissue perfusion.

Correct answer: C

Rationale: Mean Arterial Pressure (MAP) is the pressure that forces blood into the tissues, averaged over the cardiac cycle. It is not the pressure of the arterial pulse (Choice A), nor does it directly reflect the stroke volume of the heart (Choice B). While MAP involves systolic and diastolic pressures, it is not simply an average of these two values as diastole lasts longer. Instead, MAP is closer to diastolic pressure plus one third of the pulse pressure. The best description of MAP is that it represents the pressure forcing blood into the tissues, averaged over the cardiac cycle.

3. Which complication of cardiac catheterization should the nurse monitor for in the initial 24 hours after the procedure?

• A. Angina at rest
• B. Thrombus formation
• C. Dizziness
• D. Falling blood pressure

Correct answer: B

Rationale: Thrombus formation is a critical complication of cardiac catheterization that the nurse should monitor for in the initial 24 hours after the procedure. A thrombus can form in the blood vessels, obstructing blood flow and potentially leading to serious consequences such as embolism or organ ischemia. While angina at rest, dizziness, and falling blood pressure are potential complications following cardiac catheterization, they are not typically associated with the immediate post-procedural period. Monitoring for thrombus formation is essential to ensure early detection and intervention, which can prevent serious complications.

4. The abbreviation ac is defined as _____________.

• A. before the meal
• B. with the meal
• C. after the meal
• D. ante cibum

Correct answer: A

Rationale: The correct answer is 'before the meal.' The abbreviation 'ac' is derived from the Latin term 'ante cibum,' which translates to 'before a meal.' Choices B, C, and D are incorrect because 'ac' does not refer to 'with the meal,' 'after the meal,' or 'ante corpis.' It specifically denotes something occurring before a meal, making option A the correct choice in this context.

5. Which of the following statements best describes footdrop?

• A. The foot is permanently fixed in the dorsiflexion position
• B. The foot is permanently fixed in the plantar flexion position
• C. The toes of the foot are permanently fanned
• D. The heel of the foot is permanently rotated outward

Correct answer: B

Rationale: Footdrop results in the foot becoming permanently fixed in a plantar flexion position, not dorsiflexion. This position points the toes downward. The client may be unable to put weight on the foot, making ambulation difficult. Footdrop can be caused by immobility or chronic illnesses that cause muscle changes, such as multiple sclerosis or Parkinson's disease. Choice A is incorrect because footdrop leads to plantar flexion, not dorsiflexion. Choice C is incorrect as it describes a different condition known as 'toe fanning.' Choice D is incorrect as it describes an external rotation of the heel, which is not a characteristic of footdrop.
