Which laboratory test would be the least effective in diagnosing a myocardial infarction?
- A. AST
- B. Troponin
- C. CK-MB
- D. Myoglobin
Correct Answer: A
Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.

To ensure safety while administering a nitroglycerine patch, what should the nurse do?
- A. Wear gloves
- B. Shave the area where the patch will be applied
- C. Wash the area thoroughly with soap and rinse with hot water
- D. Apply the patch to the buttocks
Correct Answer: A
Rationale: To protect herself, the nurse should wear gloves when applying a nitroglycerine patch or cream. Answer B is incorrect because shaving the area where the patch will be applied might abrade the skin, increasing the risk of irritation. Answer C is incorrect because washing with hot water can vasodilate the skin, potentially increasing the absorption of nitroglycerine. Nitroglycerine patches should be applied to areas above the waist, making answer D incorrect as applying it to the buttocks is not recommended.
In which age group does the highest incidence of child abuse occur?
- A. Birth-3 years old
- B. 4-6 years old
- C. 6-10 years old
- D. More than 10 years old
Correct Answer: A
Rationale: The correct answer is 'Birth-3 years old.' Children between birth and 3 years of age have the highest rates of victimization (at 16 per 1,000 children). This age group is most vulnerable due to their dependency and inability to report or protect themselves effectively. Child abuse can occur at any age, but statistics show that infants and toddlers are at the highest risk due to their developmental stage and reliance on caregivers. Choices B, C, and D are incorrect because while child abuse can happen at any age, the prevalence is highest among children in the 0-3 age group.
A 24-year-old female client is scheduled for surgery in the morning. What is the primary responsibility of the nurse?
- A. Taking the vital signs
- B. Obtaining the permit
- C. Explaining the procedure
- D. Checking the lab work
Correct Answer: A
Rationale: The primary responsibility of the nurse is to take the vital signs before any surgery. This action helps assess the client's baseline condition and identify any abnormalities that need addressing before the procedure. Obtaining the permit (choice B) is typically handled by administrative staff, explaining the procedure (choice C) is usually done by the healthcare provider performing the surgery, and checking the lab work (choice D) is often part of the pre-operative assessment conducted by the healthcare provider. Therefore, in this context, these actions are not the primary responsibility of the nurse.
The client with schizophrenia has become disruptive and requires seclusion. Which staff member can institute seclusion?
- A. The security guard
- B. The registered nurse
- C. The licensed practical nurse
- D. The nursing assistant
Correct Answer: B
Rationale: The registered nurse is the correct choice to institute seclusion for a client with schizophrenia. In healthcare settings, only a registered nurse or a physician can legally initiate seclusion. The security guard, licensed practical nurse, and nursing assistant do not have the authority to carry out this action. Therefore, options A, C, and D are incorrect.
The nurse who was not promoted then went to the utility room and slammed several cupboard doors while looking for Kleenex. This behavior exemplifies:
- A. displacement.
- B. sublimation
- C. conversion.
- D. reaction formation.
Correct Answer: A.
Rationale: Displacement unconsciously transfers emotions associated with a person, object, or situation to another less threatening person, object, or situation. In this scenario, the nurse slammed doors instead of expressing anger towards the promoted nurse or the administrator who made the promotion decision. Sublimation is the unconscious process of substituting constructive activity for unacceptable impulses. Since slamming cupboard doors is not a constructive activity, this choice is incorrect. Conversion involves transforming anxiety into physical symptoms, which is not demonstrated in the given behavior. Reaction formation keeps unacceptable feelings or behaviors out of awareness by displaying the opposite feeling or behavior, which is not the case here.
