Which of the following would be considered an abnormal count for a radial pulse?
- A. 64 beats per minute
- B. 72 beats per minute
- C. 58 beats per minute
- D. 88 beats per minute
Correct Answer: C
Rationale: The correct answer is C (58 beats per minute) as it falls below the normal range of 60-100 beats per minute for an adult radial pulse. A pulse rate lower than 60 could indicate bradycardia or an underlying heart condition. Choices A, B, and D fall within the normal range, making them incorrect. A pulse rate of 64, 72, or 88 beats per minute would be considered normal and not abnormal.

A ______ lists the tasks that nursing assistants are permitted to perform as allowed by state or federal law.
- A. Procedure manual
- B. Cover letter
- C. Scope of practice
Correct Answer: C
Rationale: The correct answer is C, Scope of practice. The scope of practice defines the roles, responsibilities, and tasks that nursing assistants are legally allowed to perform. It is set by state or federal laws to ensure patient safety and quality care. A procedure manual (A) typically outlines specific steps for performing tasks but does not specify legal limitations. A cover letter (B) is a document used in job applications and is not related to defining nursing assistant tasks. Choice D is not provided.
A resident should place a cane about ___________ inches in front of his stronger leg.
- A. 8 inches
- B. 12 inches
- C. 14 inches
- D. 6 inches
Correct Answer: B
Rationale: The correct answer is B: 12 inches. Placing the cane 12 inches in front of the stronger leg provides optimal support and stability, allowing the resident to maintain balance and reduce the risk of falls. Placing it too close (options A and D) may not provide enough support, while placing it too far (option C) could lead to instability. The 12-inch placement ensures proper weight distribution and alignment with the body, making it the most effective choice for using a cane safely and effectively.
The stage of dying in which a person believes “yes me
- A. but…..†is called
- B. Depression
- C. Denial
- D. Acceptance
Correct Answer: D
Rationale: The correct answer is D: Acceptance. In the stages of dying proposed by Elisabeth Kubler-Ross, acceptance is the final stage. This stage involves coming to terms with one's mortality and finding peace with the situation. It signifies a readiness to die without fear or resistance. In contrast, denial (choice C) involves refusing to accept the reality of impending death, while depression (choice B) typically occurs after denial when the person starts to feel sad about their situation. Choice A is not a stage in the Kubler-Ross model and does not align with the progression of emotions in facing death.
A disorder that is related to the absorption of vitamin B12 is ___________.
- A. Pulmonary edema
- B. Congestive heart failure
- C. Pernicious anemia
- D. Phlebitis
Correct Answer: C
Rationale: The correct answer is C: Pernicious anemia. Pernicious anemia is caused by the body's inability to absorb vitamin B12, leading to a deficiency in this essential nutrient. Vitamin B12 is crucial for the production of red blood cells, and its deficiency can result in anemia. Pulmonary edema (A) is excess fluid in the lungs, congestive heart failure (B) is a heart condition, and phlebitis (D) is inflammation of a vein, none of which are directly related to vitamin B12 absorption.
While evaluating the twelve-lead electrocardiogram tracing of your 66-year-old cardiac history patient for the possibility of an acute myocardial infarction, you note the presence of deep symmetrically inverted T waves. Which of the following is most likely the cause of this abnormal finding?
- A. Necrosis
- B. Ischemia
- C. Hyperkalemia
- D. Hypokalemia
Correct Answer: B
Rationale: The correct answer is B: Ischemia. Deep symmetrically inverted T waves on an ECG are indicative of myocardial ischemia, where the heart muscle is not receiving enough oxygen-rich blood. This can lead to reversible changes in the ECG tracing. Ischemia is a common cause of T wave changes in patients with a cardiac history, suggesting ongoing heart strain. Necrosis (choice A) would typically present with pathological Q waves on ECG, not T wave inversions. Hyperkalemia (choice C) may cause peaked T waves, not symmetrically inverted ones. Hypokalemia (choice D) can lead to flattened or U-shaped T waves, not deep symmetric inversions.
