Following chemotherapy, a patient is being closely monitored for tumor lysis syndrome. Which laboratory value requires particular attention?
- A. Platelet count.
- B. Electrolytes.
- C. Hemoglobin.
- D. Hematocrit.
Correct Answer: B
Rationale: Electrolyte imbalances, particularly hyperkalemia and hyperuricemia, are hallmark features of tumor lysis syndrome and must be closely monitored.

For a patient who is experiencing side effects of radiation therapy, which task would be the most appropriate to delegate to the nursing assistant?
- A. Assist the patient to identify patterns of fatigue.
- B. Recommend participation in a walking program.
- C. Report the amount and type of food consumed from the tray.
- D. Check the skin for redness and irritation after the treatment.
Correct Answer: C
Rationale: Monitoring food intake is a straightforward task suitable for a nursing assistant, while identifying fatigue patterns or recommending exercise requires more clinical expertise.
A 25-year-old client is admitted for a tonsillectomy and informs the nurse of having had episodes of muscle cramps, weakness, and an unexplained temperature elevation. Many years ago, the client's father died shortly after surgery subsequent to developing a high fever. The surgeon has ordered dantrolene sodium (Dantrium) prophylactically prior to the tonsillectomy to reduce the risk of:
- A. a postoperative infection.
- B. malignant hyperthermia.
- C. neuroleptic malignant syndrome.
- D. a postoperative fever.
Correct Answer: B
Rationale: Dantrolene sodium (Dantrium) is a peripheral skeletal muscle relaxant and would have no effect on a postoperative infection. Dantrolene sodium (Dantrium) is indicated prophylactically for clients with malignant hyperthermia or with a family history of the disorder. The mortality rate for malignant hyperthermia is high. Neuroleptic malignant syndrome is an exercise-induced muscle pain and spasm and is not related to malignant hyperthermia. Dantrolene sodium (Dantrium) is a peripheral skeletal muscle relaxant and would have no effect on a postoperative fever.
What is the best method of controlling exposure to illness in any occupational environment?
- A. Use of masks
- B. Developing prevention programs
- C. Early diagnosis of illness
- D. Developing rehabilitation programs
Correct Answer: B
Rationale: Prevention programs address root causes, minimizing exposure risks.
Exercise can improve circulation and cardiovascular fitness by decreasing
- A. The number of small blood vessels throughout the body
- B. The heart rate and blood pressure
- C. High-density lipoproteins (HDL) in the blood
- D. The body’s breathing capacity
Correct Answer: B
Rationale: The correct answer is B because exercise can improve circulation and cardiovascular fitness by reducing the heart rate and blood pressure. When we exercise, our heart becomes more efficient at pumping blood, leading to a lower resting heart rate and reduced blood pressure. This helps improve circulation and strengthens the cardiovascular system.
Explanation for why the other choices are incorrect:
A: The number of small blood vessels throughout the body - Exercise actually promotes the growth of new blood vessels, improving circulation.
C: High-density lipoproteins (HDL) in the blood - Exercise can increase HDL levels, which is beneficial for heart health.
D: The body’s breathing capacity - Exercise can improve lung function and increase breathing capacity, but it is not directly related to circulation or cardiovascular fitness.
A client in a clinic presents with an acute asthma exacerbation. Which of the following medications should reduce the symptoms?
- A. Cromolyn via a metered-dose inhaler
- B. Montelukast orally
- C. Budesonide via a dry-powder inhaler
- D. Albuterol via a jet nebulizer
Correct Answer: D
Rationale: The correct answer is D: Albuterol via a jet nebulizer. Albuterol is a short-acting beta agonist that works by relaxing the muscles in the airways, helping to open them up and improve airflow. When administered via a nebulizer, it provides quick relief during an acute asthma exacerbation by directly targeting the airways. Cromolyn (A) is a mast cell stabilizer that is used for preventing asthma symptoms, not for acute exacerbations. Montelukast (B) is a leukotriene receptor antagonist that is used for maintenance therapy, not for immediate relief. Budesonide (C) is an inhaled corticosteroid used for long-term control of asthma, not for acute symptom relief.
