The client with myasthenia gravis has become increasingly weaker. The physician prepares to identify whether the client is reacting to an overdose of the medication (cholinergic crisis) or an increasing severity of the disease (myasthenic crisis). An injection of edrophonium (Tensilon) is administered. Which of the following would indicate that the client is in cholinergic crisis?
- A. No change in the condition
- B. An improvement of the weakness
- C. Complaints of muscle spasms
- D. A temporary worsening of the condition
Correct Answer: B
Rationale: The correct answer is B: An improvement of the weakness. Edrophonium is a short-acting cholinesterase inhibitor that helps differentiate between myasthenic and cholinergic crises in myasthenia gravis. In cholinergic crisis, there is an overdose of cholinesterase inhibitors leading to excessive acetylcholine at the neuromuscular junction, causing muscle weakness. Administering edrophonium will temporarily improve muscle weakness in cholinergic crisis due to the increased availability of acetylcholine. The other choices are incorrect because: A: No change suggests the client is not in cholinergic crisis. C: Complaints of muscle spasms are more indicative of myasthenic crisis. D: A temporary worsening of the condition is not expected in cholinergic crisis.

Several days before admission, a client reports finding a small lump in the left breast near the nipple. What should the nurse tell the client to do?
- A. Inform the physician immediately
- B. Check the area after the next menstrual
- C. Squeeze the nipple to check for period
- D. Put a heating pad on the area to reduce inflammation
Correct Answer: A
Rationale: The correct answer is A: Inform the physician immediately. This is important because finding a lump in the breast could be a sign of breast cancer, so prompt medical evaluation is crucial. Checking after the next menstrual cycle (B) may delay diagnosis and treatment. Squeezing the nipple (C) can cause harm and is not a reliable method for assessing a lump. Using a heating pad (D) is not recommended as it may mask symptoms and delay proper evaluation. Early detection and intervention are key in improving outcomes for breast cancer.
Which instruction about insulin administration should the nurse give to a client?
- A. “Always follow the same order when drawing the different insulin into the syringe.”
- B. “Shake the vial before withdrawing the insulin.”
- C. “Store unopened vials of insulin in the freezer at temperatures well below freezing.”
- D. “Discard the intermediate-acting insulin if it disappears cloudy.”
Correct Answer: A
Rationale: The correct answer is A because maintaining consistency in the order of drawing different types of insulin into the syringe helps prevent medication errors. When mixing insulins, drawing them in the same sequence ensures the correct dose and prevents contamination.
Explanation:
A: Following the same order ensures accurate dosing and minimizes the risk of mixing up insulins.
B: Shaking the vial can cause air bubbles which can affect the accuracy of the dose.
C: Storing insulin in the freezer can damage the medication and alter its effectiveness.
D: Cloudiness in intermediate-acting insulin is normal and does not indicate it should be discarded.
Before, during and after seizure. The nurse knows that the patient is ALWAYS placed in what position?
- A. Low fowler’s
- B. Modified trendelenburg
- C. Side lying
- D. Supine NERVOUS SYSTEM
Correct Answer: C
Rationale: The correct answer is C: Side lying position. This position helps prevent aspiration of secretions and promotes drainage from the mouth during and after a seizure. Placing the patient in a side lying position also helps prevent injury from falling and facilitates monitoring of the patient's airway.
Incorrect choices:
A: Low fowler's - This position does not provide optimal airway protection and may increase the risk of aspiration during a seizure.
B: Modified trendelenburg - This position may worsen the patient's airway patency and does not facilitate drainage of secretions.
D: Supine - Placing the patient in a supine position can lead to aspiration and compromise the airway, especially during a seizure.
Summary: The side lying position is the most appropriate choice as it ensures airway protection, facilitates drainage, and reduces the risk of aspiration during and after a seizure.
Antimetabolites are a diverse group of antineoplastic agents that interfere with various metabolic actions of the cell. The mechanism of action of antimetabolites interferes with:
- A. Cell division or mitosis during the M phase of the cell cycle.
- B. Normal cellular processes during the S phase of the cell cycle.
- C. The chemical structure of deoxyribonucleic acid (DNA) and chemical binding between DNA molecules (cell cycle-nonspecific).
- D. One or more stages of ribonucleic acid (RNA) synthesis, DNA synthesis, or both (cell cycle- nonspecific).
Correct Answer: D
Rationale: The correct answer is D because antimetabolites interfere with the synthesis of nucleic acids (RNA and/or DNA), affecting multiple stages of RNA and DNA synthesis. This disruption hinders cell division and leads to cell death. Choices A and B are incorrect because antimetabolites do not specifically target cell division during the M phase or normal cellular processes during the S phase. Choice C is also incorrect because antimetabolites primarily target nucleic acid synthesis rather than altering the chemical structure of DNA or the binding between DNA molecules.
A hospital’s wound nurse consultant made a recommendation for nurses on the unit about how to care for the patient’s dressing changes. Which action should the nurses take next?
- A. Include dressing change instructions and frequency in the care plan.
- B. Assume that the wound nurse will perform all dressing changes.
- C. Request that the health care provider look at the wound.
- D. Encourage the patient to perform the dressing changes.
Correct Answer: A
Rationale: The correct answer is A: Include dressing change instructions and frequency in the care plan. This is the correct action because it ensures consistency in care and communication among the nursing team. By documenting the dressing change instructions and frequency in the care plan, all nurses will have clear guidance on how to perform the dressing changes correctly and at the appropriate intervals. This promotes continuity of care and helps prevent errors or omissions in the dressing change process.
Option B is incorrect as it is not realistic to expect the wound nurse to perform all dressing changes. Option C is unnecessary unless there are specific concerns requiring the health care provider's attention. Option D is not appropriate as encouraging the patient to perform dressing changes may not be safe or feasible depending on the patient's condition.
