What does the term 'Afferent Nerve' mean?
- A. Carrying an impulse to the brain
- B. Carrying an impulse away from the brain
- C. Carrying impulses to the motor neurons of the appendicular muscles
- D. None of the above
Correct Answer: A
Rationale: The correct answer is 'Carrying an impulse to the brain.' Afferent nerves are sensory nerves that carry signals from sensory receptors towards the central nervous system, including the brain. Choice B, 'Carrying an impulse away from the brain,' is incorrect as this describes efferent nerves which carry signals from the central nervous system to muscles and glands. Choice C, 'Carrying impulses to the motor neurons of the appendicular muscles,' is incorrect as it describes a different type of nerve function. Choice D, 'None of the above,' is incorrect as the correct definition of afferent nerve is indeed 'Carrying an impulse to the brain.'

Which of the following bony landmarks is described as a large, blunt, irregularly shaped process found on the lateral aspect of the proximal femur?
- A. Tubercle
- B. Tuberosity
- C. Condyle
- D. Trochanter
Correct Answer: D
Rationale: The correct answer is D: Trochanter. The Greater Trochanter is located on the lateral aspect of the proximal femur and is a large, blunt, irregularly shaped bony process. It serves as an important attachment site for many muscles of the legs, providing leverage and movement. Choice A, Tubercle, is a small rounded projection, usually for the attachment of a ligament or tendon. Choice B, Tuberosity, is a large rounded projection, also typically for muscle attachment. Choice C, Condyle, refers to a rounded articular surface at the end of a bone, usually involved in joints.
You have been assigned to take an apical pulse for one of the patients on the nursing unit. How will you do this?
- A. You will place the stethoscope over the heart and listen for any irregular beats.
- B. You will place the stethoscope over the heart and count the beats per minute.
- C. You will place your fingertip over the patient's wrist and feel for any irregular beats.
- D. You will place your fingertip over the patient's wrist and count the beats per minute.
Correct Answer: B
Rationale: To take an apical pulse accurately, you should place the stethoscope over the heart and count the number of beats per minute. This method provides a precise assessment of the heart rate. While listening for irregular beats is essential for assessing the heart's rhythm, the primary objective of taking an apical pulse is to determine the heart rate. Choices C and D are incorrect because the apical pulse is not taken at the wrist; instead, it is obtained by auscultating at the apex of the heart, usually at the point where the fifth intercostal space meets the midclavicular line.
Which of the following scenarios provides an example of a healthcare professional overcoming a barrier to communication?
- A. A healthcare professional uses a visual aid to explain how to conduct a fingerstick glucose test to a patient with visual impairment.
- B. A healthcare professional writes down instructions for a patient who is hearing impaired.
- C. A healthcare professional raises their voice when speaking to a patient who does not speak English.
- D. A healthcare professional uses medical jargon while conversing with a minor.
Correct Answer: B
Rationale: Overcoming barriers to communication in healthcare involves utilizing methods of communication that are accessible and understandable to the recipient. In the scenario provided, writing down instructions for a patient who is hearing impaired is an effective way to ensure clear communication and overcome the obstacle of hearing impairment. This method allows the patient to visually comprehend the information provided.
Choice A is incorrect because using a visual aid for a visually impaired patient, not a hearing-impaired patient, would be more appropriate. Choice C is incorrect as raising one's voice does not address the language barrier effectively and may not enhance understanding. Choice D is incorrect as using complex medical terms with a minor may lead to confusion and hinder effective communication.
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.
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.
