A client is scheduled for a prostatectomy, and the anesthesiologist plans to use a spinal (sub-arachnoid) block during surgery. In the operating room, the nurse positions the client according to the anesthesiologist’s instructions. Why does the client require special positioning for this type of anesthesia?
- A. To prevent confusion
- B. To prevent cerebrospinal fluid (CSF)
- C. To prevent seizures leakage
- D. To prevent cardiac arrhythmias
Correct Answer: B
Rationale: The correct answer is B: To prevent cerebrospinal fluid (CSF) leakage.
Rationale: During a spinal block, the anesthesiologist injects anesthesia into the subarachnoid space, which contains CSF. Proper positioning ensures that the anesthesia stays in place and prevents leakage of CSF, which could lead to complications such as post-dural puncture headache.
Incorrect choices:
A: To prevent confusion - Irrelevant to the procedure.
C: To prevent seizures leakage - Seizures are not a concern with spinal blocks.
D: To prevent cardiac arrhythmias - Cardiac arrhythmias are not directly related to spinal blocks.

A client with advanced liver cancer is scheduled for chemotherapy. As part of the chemotherapy regimen, the nurse expects the physician to prescribe:
- A. Fluoxymesterone (Halotestin)
- B. Fluorouracil (5-fluorouracil, 5 FU
- C. Tamoxifen (Nolvadex) [Fluoroplex])
- D. Megestrol (Megace)
Correct Answer: B
Rationale: The correct answer is B: Fluorouracil (5-fluorouracil, 5-FU). Fluorouracil is a commonly used chemotherapy drug for treating advanced liver cancer. It works by inhibiting the growth of cancer cells. This drug is specifically effective in targeting rapidly dividing cells, which is a characteristic of cancer cells. Fluorouracil is often used in combination with other chemotherapy drugs to improve treatment outcomes.
Summary of other choices:
A: Fluoxymesterone (Halotestin) - This is an androgen hormone used to treat certain types of breast cancer, not liver cancer.
C: Tamoxifen (Nolvadex) - This is a hormonal therapy drug used in breast cancer, not liver cancer.
D: Megestrol (Megace) - This is a hormonal therapy drug used for certain types of cancers, but not typically for liver cancer.
Which action by the nurse is appropriate?
- A. Observe the patient for abnormal bleeding.
- B. Notify the physician and expect an order to increase the warfarin dose.
- C. Advise the patient to double today’s dose of warfarin.
- D. Administer Vit. K per protocol.
Correct Answer: A
Rationale: The correct answer is A because observing the patient for abnormal bleeding is an appropriate action to monitor for potential complications of warfarin therapy. This aligns with the nursing role in assessing and monitoring patient responses to treatment.
B is incorrect as increasing warfarin dose without physician order can lead to adverse effects. C is incorrect as altering the dose without medical advice can be dangerous. D is incorrect as administering Vitamin K would counteract the effects of warfarin, which is used to prevent blood clotting.
A client who is receiving cyclosporine (Sandimmune) must practice good oral hygiene, including regular brushing and flossing of the teeth, to minimize gingival hyperplasia during long-term therapy with certain drugs. Which of the following drug falls into this category?
- A. Procainamide (Pronestyl)
- B. Phenytoin (Dilantin)
- C. Azathioprine (Imuran)
- D. Allopurinol (Zyloprim)
Correct Answer: B
Rationale: The correct answer is B: Phenytoin (Dilantin). Phenytoin is known to cause gingival hyperplasia as a side effect, which can be minimized with good oral hygiene practices. Procainamide, Azathioprine, and Allopurinol are not associated with gingival hyperplasia. Therefore, the client receiving cyclosporine should focus on practicing good oral hygiene specifically when taking Phenytoin to minimize the risk of developing gingival hyperplasia.
A registered nurse administers pain medication to a patient suffering from fractured ribs. Which type of nursing intervention is this nurse implementing?
- A. Collaborative
- B. Independent
- C. Interdependent
- D. Dependent
Correct Answer: D
Rationale: The correct answer is D: Dependent. In this scenario, the nurse is administering pain medication based on a healthcare provider's prescription, which demonstrates a dependent nursing intervention. The nurse is reliant on the provider's order to carry out this action. Collaborative interventions involve working with other healthcare professionals, independent interventions are actions that nurses can initiate without supervision, and interdependent interventions involve mutual goal-setting and decision-making among healthcare team members.
Which of the following communication methods is not an option for a patient following laryngectomy surgery?
- A. Placing a finger over the stoma
- B. Using a picture board
- C. Using a special valve that diverts air into
- D. Learning esophageal speech the oesophagus
Correct Answer: D
Rationale: The correct answer is D because learning esophageal speech involves creating sound by pushing air from the mouth into the esophagus and then releasing it. Following laryngectomy surgery, the patient's larynx is removed, making it impossible to produce sound in this manner. Placing a finger over the stoma (A) allows the patient to redirect air through the mouth for speech, using a picture board (B) enables communication through written or visual cues, and using a special valve that diverts air into the trachea (C) allows for voice rehabilitation. In summary, options A, B, and C are valid communication methods post-laryngectomy surgery, while option D is not feasible due to the absence of the larynx.
