A nurse is discussing adverse reactions to pain medications in older adult clients with a newly licensed nurse.
Which of the following findings should the nurse include as risk factors for an adverse drug reaction? (Select all that apply)
Decreased percentage of body fat.
Multiple health problems.
Increased rate of absorption.
Polypharmacy.
Decreased renal function.
Correct Answer : B,D,E
Older adults are at higher risk of adverse drug reactions due to multiple health problems, polypharmacy, and decreased renal function.
These factors can affect the pharmacokinetics and pharmacodynamics of pain medications and increase the likelihood of drug interactions, overdosage, or toxicity.
Choice A is wrong because the decreased percentage of body fat does not increase the risk of adverse drug reactions in older adults.
In fact, an increased percentage of body fat can alter the distribution and elimination of some drugs.
Choice C is wrong because an increased rate of absorption does not increase the risk of adverse drug reactions in older adults.
In fact, decreased rate of absorption can occur due to reduced gastric motility and blood flow.

Correct Answer is A
Explanation
Hyponatremia is a condition where the sodium level in the blood is too low, which can cause confusion, lethargy, seizures, and coma. A hypertonic solution is a fluid that has a higher concentration of solutes than the blood, which can help raise the sodium level and reduce the brain swelling caused by hyponatremia. Therefore, improved cognition indicates that the treatment is effective.
Choice B. Cardiac arrhythmias absent.
Cardiac arrhythmias are not a common symptom of hyponatremia unless it is severe or rapid in onset.
Therefore, their absence does not necessarily indicate that the treatment is effective.
Choice C. Decreased vomiting.
Vomiting can be a cause or a consequence of hyponatremia, depending on the underlying condition.
Decreased vomiting may indicate that the patient is less nauseated, but it does not reflect the sodium level or the brain status.
Choice D. Absent Chvostek’s sign.
Chvostek’s sign is a facial twitching that occurs when tapping on the cheek, which indicates hypocalcemia (low calcium level).
It is not related to hyponatremia or hypertonic solution.
Normal ranges for sodium are 135 to 145 mEq/L and for calcium are 8.5 to 10.5 mg/dL.
Correct Answer is A
Explanation
An aPTT of 90 seconds is much higher than the normal range of 30-40 seconds, which means the blood takes longer to clot and the client is at risk of bleeding. An increased pulse rate is a sign of blood loss and shock.
Choice B is wrong because increased blood pressure is not a sign of bleeding, but rather a sign of hypertension or stress.
Choice C is wrong because decreased temperature is not a sign of bleeding, but rather a sign of hypothermia or infection.
Choice D is wrong because decreased respiratory rate is not a sign of bleeding, but rather a sign of respiratory depression or sedation.
