1. Which type of cells secrete insulin?
- A. alpha cells
- B. beta cells
- C. CD4 cells
- D. helper cells
Correct answer: B
Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.
2. When teaching a client about anti-retroviral therapy for human immunodeficiency virus (HIV), the PN should emphasize:
- A. When started, therapy must not be interrupted to prevent viral resistance.
- B. When started, therapy must not be interrupted to prevent opportunistic infection.
- C. Therapy should not be interrupted for one day each month to prevent toxicity.
- D. Therapy should not be interrupted for one week every three months to prevent toxicity.
Correct answer: A
Rationale: When teaching a client about anti-retroviral therapy for HIV, it is crucial to emphasize that therapy must not be interrupted to prevent viral resistance. HIV mutates rapidly, and any interruption can lead to the emergence of resistant strains, compromising treatment effectiveness. Choice B is incorrect because keeping the virus in check with anti-retrovirals helps the client's immune system fight off opportunistic infections. Choices C and D are incorrect because therapy should not be interrupted for any reason. If toxicity occurs, the healthcare provider may adjust the treatment regimen by prescribing alternative anti-retroviral drugs.
3. A healthcare professional is reviewing a patient's current Lithium levels. Which of the following values is outside the therapeutic range?
- A. 1.0 mEq/L
- B. 1.1 mEq/L
- C. 1.2 mEq/L
- D. 1.3 mEq/L
Correct answer: D
Rationale: The correct answer is 1.3 mEq/L. The therapeutic range for Lithium levels typically falls between 0.6 to 1.2 mEq/L. Values below or above this range can lead to suboptimal treatment outcomes or toxicity. Choices A, B, and C are within the therapeutic range of 1.0-1.2 mEq/L, making them appropriate levels for patient care.
4. The manic client has just interrupted the group session with the counselor for the 4th time, explaining that she already knows this information on 'dealing with others when you are down' and constantly gets up and goes to the front. What should the nurse do at this time?
- A. Engage the client to walk with you to make another pot of coffee
- B. Ask the client to reflect on their behavior to determine if it is appropriate
- C. Ask the group to tell the client how they feel when she interrupts
- D. Instruct the client to perform jumping jacks and count aloud to get rid of some energy
Correct answer: A
Rationale: In this situation, it is important to redirect the client's energy and focus. Engaging the client in a purposeful activity like making another pot of coffee can help distract them from disruptive behavior and provide an outlet for their excess energy. This choice also helps in maintaining a therapeutic environment by involving the client in a constructive task. Asking the client to reflect on their behavior (Choice B) might not be effective during a manic episode as the client may not be in a state to critically analyze their actions. Asking the group to tell the client how they feel (Choice C) can escalate the situation and may not be appropriate in this context. Instructing the client to perform jumping jacks and count aloud (Choice D) may not address the underlying issue of disruptive behavior and may not be suitable for the current situation.
5. In alcoholics with anemia:
- A. Pernicious anemia is more common than folic acid deficiency.
- B. Iron deficiency and folic acid deficiency can coexist.
- C. The alcohol interferes with iron absorption.
- D. Oral vitamin replacement is contraindicated.
Correct answer: B
Rationale: In alcoholics with anemia, iron deficiency and folic acid deficiency can coexist due to poor dietary intake and malabsorption issues associated with chronic alcohol consumption. Pernicious anemia, primarily related to vitamin B12 deficiency, is not commonly seen in alcoholics. While alcohol can interfere with iron absorption, it is not the sole factor contributing to anemia in alcoholics. Oral vitamin replacement is not contraindicated in alcoholics with anemia; however, it may be less effective due to absorption issues related to alcohol consumption.
