1. When a client is taking Somatropin to stimulate growth, what should the healthcare provider monitor the client's urine for?
- A. Bilirubin
- B. Protein
- C. Potassium
- D. Calcium
Correct answer: D
Rationale: When a client is taking Somatropin to stimulate growth, monitoring urine for calcium is essential. Somatropin can lead to increased calcium levels in the urine, potentially increasing the risk of renal calculi formation. Therefore, assessing for calcium in the urine helps in early detection and prevention of this complication. Monitoring for bilirubin, protein, or potassium in the urine is not directly related to the effects of Somatropin and would not provide relevant information in this context.
2. A toddler is being admitted to the hospital after an Acetaminophen overdose. Which of the following medications should the nurse anticipate administering to this patient?
- A. Acetylcysteine
- B. Pegfilgrastim
- C. Misoprostol
- D. Naltrexone
Correct answer: A
Rationale: In cases of Acetaminophen overdose, acetylcysteine is the antidote of choice. Acetylcysteine helps prevent liver damage by replenishing depleted glutathione levels, which is essential for detoxifying acetaminophen metabolites. Pegfilgrastim is a medication used to stimulate white blood cell production, Misoprostol is a medication for preventing stomach ulcers, and Naltrexone is used for treating opioid addiction and alcoholism, but none of these are indicated for Acetaminophen overdose.
3. What does it mean when a medication has a half-life?
- A. It only lasts for 30 minutes after the medication is given
- B. How long it takes for half of the dose to be eliminated from the bloodstream
- C. It is the peak of how effective the medicine is
- D. Drug is greatly reduced before it reaches the systemic circulation
Correct answer: B
Rationale: When a medication has a half-life, it refers to the time it takes for half of the dose to be eliminated from the bloodstream. This parameter is crucial in understanding the duration of action and dosing intervals for medications in clinical practice. Choice A is incorrect as the half-life is not about how long the medication lasts but about elimination from the body. Choice C is incorrect because the half-life is not about the peak effectiveness of the medicine. Choice D is incorrect as it does not accurately define the concept of half-life.
4. A client has a new prescription for Clozapine. Which of the following statements should the nurse include in the teaching?
- A. You should have a high-carbohydrate snack between meals and at bedtime.
- B. You are likely to develop hand tremors if you take this medication for a long period of time.
- C. You may experience temporary numbness of your mouth after each dose.
- D. You should have your white blood cell count monitored every week.
Correct answer: D
Rationale: Clozapine has a risk for fatal agranulocytosis, making weekly monitoring of the client's white blood cell (WBC) count essential to detect any potential issues early. This monitoring helps in managing the risk and ensuring the client's safety while on clozapine.
5. A healthcare provider is preparing to administer an IV bolus of Morphine to a client for pain management. Which of the following assessments is the healthcare provider's priority?
- A. Respiratory rate
- B. Pain level
- C. Blood pressure
- D. Level of consciousness
Correct answer: A
Rationale: The priority assessment for a healthcare provider preparing to administer an IV bolus of Morphine is the client's respiratory rate. Morphine can cause respiratory depression as a significant adverse effect, so monitoring the respiratory rate is crucial to detect any signs of respiratory compromise and intervene promptly. Assessing the respiratory rate takes precedence over other assessments because respiratory depression can lead to serious complications. While pain level, blood pressure, and level of consciousness are important assessments, they are not the priority when administering Morphine, as the risk of respiratory depression is a more immediate concern.
