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 client must use a non-rebreathing oxygen mask. Which of the following statements is true regarding this type of mask?

• A. A non-rebreather can provide an FiO2 of 40%.
• B. A client should breathe through his or her mouth when using a non-rebreather.
• C. A non-rebreather offers a reservoir from which the client inhales.
• D. The mask of a non-rebreather should be changed every 3 hours.

Correct answer: A

Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.

3. You are caring for a Hispanic patient who is scheduled for surgery in the morning. A member of the surgery staff is in a hurry when she visits the patient to obtain surgical consent. You know that the patient speaks limited English and can see that he does not really understand what's being said. What is the most appropriate next action?

• A. Call a family member to interpret
• B. Consult the hospital translator to assist
• C. Allow the consent to be signed
• D. Ask the staff member to come back later

Correct answer: B

Rationale: Consulting the hospital translator is the most reliable means of ensuring accuracy in the information that the patient is receiving. Family members can be helpful, but they may have difficulty understanding the medical procedures well enough to explain them accurately and may misinterpret the message. Relying on family members could lead to misunderstandings or miscommunication. Allowing the consent to be signed without ensuring the patient's full understanding could pose risks to the patient's well-being. Asking the staff member to come back later delays the essential communication process needed before surgery. Therefore, consulting the hospital translator is the best course of action to ensure clear and accurate communication, especially in critical healthcare decisions like surgical consent.

4. Which of the following conditions increases a client's risk of aspiration of stomach contents?

• A. A client is in restraints
• B. A client has a scaphoid abdomen
• C. A client is lying prone
• D. More than one answer is correct

Correct answer: A

Rationale: A client in restraints is at an increased risk of aspiration of stomach contents. When a client is restrained, they may be unable to effectively move or turn their body if they begin to vomit, which can lead to aspiration. This lack of mobility can hinder their ability to protect their airway. On the other hand, a scaphoid abdomen, which is sunken or hollowed, is not a direct risk factor for aspiration. Additionally, lying prone, facing downward, does not necessarily increase the risk of aspiration, as aspiration is more likely when lying supine (facing upward). Therefore, the correct answer is that a client is in restraints.

5. A client diagnosed with schizophrenia is slow to respond and appears to be listening to unseen others. Which medication should a nurse expect a physician to order to address this type of symptom?

• A. Haloperidol (Haldol) to address the negative symptom
• B. Clonazepam (Klonopin) to address the positive symptom
• C. Risperidone (Risperdal) to address the positive symptom
• D. Clozapine (Clozaril) to address the negative symptom

Correct answer: C

Rationale: The correct medication to address the symptom described, where the client is slow to respond and appears to be listening to unseen others, is Risperidone (Risperdal). Risperidone is an atypical antipsychotic that is commonly used to manage positive symptoms of schizophrenia. Positive symptoms can include hallucinations, delusions, and disorganized thinking. Haloperidol (Haldol) and Clozapine (Clozaril) are typically used for addressing negative symptoms, such as lack of motivation or social withdrawal. Clonazepam (Klonopin) is a benzodiazepine primarily used for anxiety disorders and seizures, not for addressing symptoms of schizophrenia.
