1. Which of the following white blood cells is the smallest and can be involved in humoral immunity?
- A. Lymphocyte
- B. Monocyte
- C. Basophil
- D. Erythrocyte
Correct answer: A
Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.
2. A nursing student is teaching a patient and family about epilepsy prior to the patient's discharge. For which statement should you intervene?
- A. "You should avoid consumption of all forms of alcohol."?
- B. "Wear your medical alert bracelet at all times."?
- C. "Protect your loved one's airway during a seizure."?
- D. "It's important to consult with your physician before taking over-the-counter medications."?
Correct answer: D
Rationale: The correct answer is, "It's important to consult with your physician before taking over-the-counter medications."? Patients with epilepsy should not take over-the-counter medications without medical advice due to potential interactions with antiepileptic drugs or triggering seizures. Choices A, B, and C are all appropriate statements for a patient with epilepsy, focusing on alcohol avoidance, wearing a medical alert bracelet, and airway protection during a seizure, respectively. Choice D is incorrect because patients with epilepsy need to be cautious about medications due to possible interactions or adverse effects, so consulting with a physician is crucial before taking over-the-counter medications.
3. The chain of infection includes the ________________.
- A. germ, agent, reservoir, exit portal, mode of transmission, entry port, and susceptible host
- B. active natural, active artificial, passive natural, and passive artificial
- C. opportunism, weakness, immunity, and colonization
- D. intrinsic, extrinsic, internal, and external transmission
Correct answer: A
Rationale: The chain, or cycle, of infection includes the germ (microorganism), agent, reservoir, exit portal, mode of transmission, entry port, and susceptible host. This sequence describes how infections are passed from one person to another. Choice B is incorrect because it refers to types of immunity, not components of the chain of infection. Choice C is also incorrect as it lists terms unrelated to the chain of infection. Choice D is incorrect as it describes transmission types, not components of the chain of infection. Understanding the chain of infection is crucial in preventing the spread of infections by breaking one or more links in the chain, such as interrupting the mode of transmission through proper hand hygiene.
4. Which of the following types of antipsychotic medications is most likely to produce extrapyramidal effects?
- A. Atypical antipsychotic drugs
- B. First-generation antipsychotic drugs
- C. Third-generation antipsychotic drugs
- D. Dopamine system stabilizers
Correct answer: B
Rationale: The correct answer is first-generation antipsychotic drugs. These drugs are potent antagonists of D2, D3, and D4 receptors, making them effective in treating target symptoms but also leading to numerous extrapyramidal side effects due to the blockade of D2 receptors. Atypical or second-generation antipsychotic drugs, as mentioned in choice A, are relatively weak D2 blockers, which results in a lower incidence of extrapyramidal side effects. Third-generation antipsychotic drugs, as in choice C, and dopamine system stabilizers, as in choice D, are not typically associated with significant extrapyramidal effects compared to first-generation antipsychotics.
5. The nurse is caring for a woman 2 hours after a vaginal delivery. Documentation indicates that the membranes were ruptured for 36 hours prior to delivery. What are the priority nursing diagnoses at this time?
- A. Altered tissue perfusion
- B. Risk for fluid volume deficit
- C. High risk for hemorrhage
- D. Risk for infection
Correct answer: D
Rationale: The correct answer is 'Risk for infection.' When membranes are ruptured for over 24 hours before delivery, there is a significantly increased risk of infection for both the mother and the newborn. Factors such as increased local cytokines, an imbalance in enzyme activity, and increased intrauterine pressure contribute to this risk. 'Altered tissue perfusion' is not the priority in this scenario as there is no indication of compromised blood flow. 'Risk for fluid volume deficit' is not the priority as there are no signs of excessive fluid loss. 'High risk for hemorrhage' is not the priority as the question does not suggest active bleeding as an immediate concern.
