1. Acyclovir (Zovirax) is the agent of choice for which of the following infections?
- A. HIV
- B. AIDS
- C. candida
- D. herpes
Correct answer: D
Rationale: Acyclovir is an antiviral medication specifically effective in treating herpes infections. It works by inhibiting the replication of the herpes virus, shortening the duration of the infection. While Acyclovir can be used in HIV and AIDS patients to treat opportunistic viral infections, it is not a primary drug for managing HIV or AIDS itself. Candida is a type of fungus, and infections caused by Candida are treated with antifungal medications, not antivirals like Acyclovir. Therefore, the correct answer is herpes.
2. Which of the following represents a normal serum potassium level?
- A. 1.5 mEq/L
- B. 3.0 mEq/L
- C. 4.0 mEq/L
- D. 6.0 mEq/L
Correct answer: C
Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).
3. Under what circumstances can an individual receive medical care without giving informed consent?
- A. when the durable power of attorney for health care is not available
- B. in an emergency, life-or-death situation
- C. when the physician is not available for discussion with the client
- D. when they (clients) are not able to speak for themselves
Correct answer: B
Rationale: An individual may receive medical care without giving informed consent in an emergency, life-or-death situation. This exception allows healthcare providers to provide immediate treatment to save a person's life or prevent serious harm when time is of the essence. Choices A, C, and D are incorrect because in all other situations, informed consent is required. The durable power of attorney for health care should be involved if available, the physician should have a discussion with the client in non-life-threatening situations, and in cases where clients are unable to speak for themselves, their designated representative or responsible party should be involved in the consent process.
4. Which of the following is not an indication for pelvic ultrasonography?
- A. to measure uterine size
- B. to detect multiple pregnancies
- C. to measure renal size
- D. to detect foreign bodies
Correct answer: C
Rationale: Pelvic ultrasonography is commonly used to assess various conditions. Choices A, B, and D are all valid reasons for performing pelvic ultrasonography. Measuring uterine size helps evaluate conditions like fibroids, while detecting multiple pregnancies is essential for prenatal care. Furthermore, identifying foreign bodies can aid in diagnosing certain conditions. However, assessing renal size is typically not a primary reason for pelvic ultrasonography, making choice C the correct answer.
5. When the healthcare provider is determining the appropriate size of a nasopharyngeal airway to insert, which body part should be measured on the client?
- A. corner of the mouth to tragus of the ear
- B. corner of the eye to top of the ear
- C. tip of the chin to the sternum
- D. tip of the nose to the earlobe
Correct answer: D
Rationale: A nasopharyngeal airway is measured from the tip of the nose to the earlobe. This measurement ensures that the airway is of the correct length to reach the nasopharynx without being too long or too short. Choices A, B, and C are incorrect as they do not provide the appropriate measurement for selecting the correct size of a nasopharyngeal airway. The distance from the corner of the mouth to the tragus of the ear (Choice A) is used to measure for an oropharyngeal airway, not a nasopharyngeal airway. Similarly, the other choices (B and C) do not correlate with the correct measurement of a nasopharyngeal airway.
