Chapter 3 : Lifespan Considerations Questions
Question 1 of 5
When discussing dosage calculation for pediatric patients with a clinical pharmacist, the nurse notes that which type of dosage calculation is used most commonly in pediatric calculations?
Correct Answer: D
Rationale: The milligram per kilogram formula, based on body weight, is the most common method of calculating doses for pediatric patients. West nomogram and Clark rule are available but less commonly used, and height-to-weight ratio is not a standard method.
Question 2 of 5
The nurse is assessing a newly admitted 83-year-old patient and determines that the patient is experiencing polypharmacy. Which statement most accurately illustrates polypharmacy?
Correct Answer: D
Rationale: Polypharmacy usually occurs when a patient has several illnesses and takes medications for each of them, possibly prescribed by different specialists who may be unaware of other treatments the patient is undergoing. It involves multiple medications, not just multiple illnesses, a single medication, or only over-the-counter drugs.
Question 3 of 5
The nurse is aware that confusion, forgetfulness, and increased risk for falls are common responses in an elderly patient who is taking which type of drug?
Correct Answer: C
Rationale: Sedatives and hypnotics often cause confusion, daytime sedation, ataxia, lethargy, forgetfulness, and increased risk for falls in the elderly. Laxatives, anticoagulants, and antidepressants may cause other adverse effects, but not the specific ones mentioned.
Question 4 of 5
For accurate medication administration to pediatric patients, the nurse must consider which of these factors?
Correct Answer: A
Rationale:
To administer medications to pediatric patients accurately, one must take into account organ maturity, body surface area, age, and weight. Renal output, body temperature, and height alone are not primary considerations for accurate medication administration.
Question 5 of 5
The nurse recognizes that an elderly patient may experience a reduction in the stomach's ability to produce hydrochloric acid. This change may result in which effect?
Correct Answer: D
Rationale: Reduction in the stomach's ability to produce hydrochloric acid is an aging-related change that results in a decrease in gastric acidity and may alter the absorption of some drugs. It does not directly cause delayed gastric emptying, increased gastric acidity, or decreased gastrointestinal motility.
