1. Which of the following isoenzymes is elevated in a client who has had a myocardial infarction?

• A. CPK-BB
• B. CPK-MM
• C. CPK-MB
• D. CPK-MI

Correct answer: C

Rationale: CPK-MB is the correct answer as it is elevated in clients who have had a myocardial infarction. CPK-BB is elevated in clients with brain damage, and CPK-MM is elevated in clients with skeletal muscle damage. CPK-MI, mentioned in the rationale, does not exist, making it an incorrect choice.

2. A child comes to the clinic with a skin rash. The maculopapular lesions are distributed around the mouth and have honey-colored drainage. The caregiver states that the rash is getting worse and seems to spread with the child's scratching. Which of the following advisory comments should be given?

• A. The history and presentation might indicate chickenpox, a highly contagious disease.
• B. The lesions might indicate a noncontagious infection that does not require isolation.
• C. The history and presentation might indicate an infectious illness called impetigo.
• D. The lesions are not contagious unless others have open wounds or lesions themselves.

Correct answer: C

Rationale: The scenario describes classic impetigo, characterized by maculopapular lesions with honey-colored drainage, typically caused by Staphylococcus aureus or Streptococcus pyogenes. Antibiotic therapy is usually indicated for impetigo. Chickenpox, a highly contagious disease, presents with a history of high fever followed by a vesicular rash, different from the described maculopapular lesions with honey-colored drainage. Choice A is incorrect as the presentation is not consistent with chickenpox. Choice B is incorrect because impetigo is contagious, especially through direct contact. Choice D is also incorrect as impetigo is a contagious skin infection regardless of others having open wounds or lesions.

3. When assessing a client with terminal cancer receiving a continuous intravenous infusion of morphine sulfate, what should the nurse check first?

• A. Temperature
• B. Respiratory status
• C. Pulse
• D. Urine output

Correct answer: B

Rationale: When assessing a client with terminal cancer receiving morphine sulfate via continuous intravenous infusion, the nurse's priority should be checking the client's respiratory status first. Morphine sulfate can lead to respiratory depression, emphasizing the need for close monitoring of breathing. While temperature, pulse, and urine output are all essential components of the assessment, ensuring adequate respiratory function takes precedence due to the potential risk of respiratory depression associated with morphine sulfate. Promptly assessing respiratory status enables early identification of any signs of respiratory distress or depression, allowing for immediate intervention if needed.

4. The nurse is teaching a teenage female about preventing the transmission of genital herpes. Which of the following statements should the nurse include?

• A. "Do not sit on toilet seats without protection."?
• B. "Oral sex can transmit the virus."?
• C. "This infection can be transmitted via intercourse even when you do not feel ill."?
• D. "Try to drink lots of fluids after sex to flush the reproductive tract."?

Correct answer: C

Rationale: Genital herpes can be transmitted through oral, genital, and anal sex. It's crucial to understand that the infection can be spread through intercourse even when symptoms are not present. Option A is incorrect because genital herpes is not transmitted through toilet seats. Option B is correct as oral sex can transmit the virus. Option D is incorrect as drinking fluids after sex does not prevent the transmission of genital herpes.

5. Which of the following syndromes associated with incomplete lesions of the spinal cord results from damage to one-half of the spinal cord?

• A. Brown-S�quard syndrome
• B. posterior cord syndrome
• C. central cord syndrome
• D. cauda equina syndrome

Correct answer: A

Rationale: Brown-S�quard syndrome is indeed associated with incomplete lesions of the spinal cord, and it specifically results from damage to one-half of the spinal cord. This syndrome manifests as ipsilateral motor paralysis, ipsilateral loss of vibration and proprioception, and contralateral loss of pain and temperature sensation. Posterior cord syndrome mainly involves the loss of proprioception and vibratory sense, while sparing motor function and pain sensation. Central cord syndrome typically presents with more weakness in the upper extremities compared to the lower extremities due to central spinal cord damage. Cauda equina syndrome affects the nerve roots at the level of the conus medullaris, leading to symptoms like lower extremity weakness, numbness, and bowel/bladder dysfunction.
