After cancer chemotherapy, a client experiences nausea and vomiting. The nurse should highest priority to which intervention?
- A. Serving small portions bland food
- B. Encouraging rhythmic breathing exercises
- C. Administering metoclopramide (Reglan) and dexamethasone (Decadron) as prescribed
- D. Withholding fluids for the first 4 to 6 hours after chemotherapy administration
Correct Answer: C
Rationale: The correct answer is C because administering antiemetic medications like metoclopramide and dexamethasone helps control nausea and vomiting post-chemotherapy. Metoclopramide acts on the gut to reduce nausea, while dexamethasone decreases inflammation and suppresses the vomiting reflex. Choice A focuses on dietary interventions but does not address the physiological cause of nausea. Choice B with breathing exercises may help some clients but does not directly address the nausea and vomiting. Choice D is incorrect as withholding fluids can lead to dehydration, which is not recommended after chemotherapy.

The nurse would monitor the client for which of the following?
- A. Trousseau’s sign
- B. Hypoglycemia
- C. Hypokalamia
- D. Respiratory changes
Correct Answer: A
Rationale: The correct answer is A: Trousseau's sign. This involves carpal spasm induced by inflating a blood pressure cuff above systolic pressure, indicating hypocalcemia. The nurse should monitor for this sign in clients at risk for low calcium levels. Hypoglycemia and hypokalemia have specific signs and symptoms not related to Trousseau's sign. Respiratory changes are nonspecific and may not be directly related to monitoring for low calcium levels.
Which of the ff is a sign or symptom characteristic of the later stages of TB?
- A. Fatigue
- B. Anorexia
- C. Hemoptysis
- D. Weight loss
Correct Answer: C
Rationale: The correct answer is C: Hemoptysis. In the later stages of TB, the infection can lead to damage in the lungs, causing blood to be coughed up (hemoptysis). This is a serious symptom indicating advanced disease progression. Fatigue (A), anorexia (B), and weight loss (D) are common symptoms of TB but can occur in earlier stages as well. Hemoptysis specifically indicates more severe lung involvement, making it characteristic of later stages.
The client with epilepsy is taking the prescribed dose of phenytoin (Dilantin) to control seizures. Results of a phenytoin blood level study reveal a level of 35 mcg/ml. Which of the following symptoms would be expected as a result of this laboratory result?
- A. Nystagmus
- B. No symptoms, because this is normal
- C. Tachycardia therapeutic level
- D. Slurred speech
Correct Answer: A
Rationale: The correct answer is A: Nystagmus. A phenytoin blood level of 35 mcg/ml is above the therapeutic range (usually 10-20 mcg/ml). Excessive levels can lead to symptoms such as nystagmus, which is an involuntary eye movement commonly seen with phenytoin toxicity. Nystagmus is a known side effect of phenytoin overdose. Choices B and C are incorrect because a level of 35 mcg/ml is not within the normal therapeutic range, so symptoms would be expected. Choice D, Slurred speech, is not typically associated with phenytoin toxicity.
Which of the following parts of neuron transmits impulses away from the cell body?
- A. Dendrite
- B. . Neurolemma
- C. Axon
- D. Synapse
Correct Answer: C
Rationale: The correct answer is C: Axon. The axon is the part of the neuron that transmits impulses away from the cell body towards other neurons, muscles, or glands. Its structure allows for the rapid transmission of electrical signals.
Rationale:
1. Dendrites receive signals and transmit them towards the cell body, so A is incorrect.
2. Neurolemma is the outermost layer of a Schwann cell, not a part of the neuron responsible for transmitting impulses, so B is incorrect.
3. The synapse is the junction between two neurons where communication occurs, not a part of the neuron transmitting impulses, so D is incorrect.
A nurse is directed to administer a hypotonic intravenous solution. The nurse expects that compensatory mechanisms associated with hypovolemia would cause all of the following symptoms except:
- A. O.45% sodium chloride
- B. 5% dextrose in water
- C. O.90% sodium chloride
- D. 5% dextrose in normal saline solution
Correct Answer: C
Rationale: The correct answer is C: 0.90% sodium chloride. When administering a hypotonic solution like 0.45% sodium chloride or 5% dextrose in water, water moves into the cells causing them to swell. This can exacerbate symptoms of hypovolemia such as low blood pressure and decreased perfusion. However, 0.90% sodium chloride is an isotonic solution and will not further exacerbate hypovolemic symptoms. Choices A, B, and D are hypotonic solutions that can worsen hypovolemic symptoms by causing cellular swelling.
