A patient with chronic pain was admitted to the hospital. The physician orders morphine sulfate 5mg PO every 4 hours. The patient states that he usually takes his home morphine prescription of 10mg every 4 hours and has been for several months. The patient is at risk for which of the following?

Physical dependence

Tolerance

Abstinence syndrome

Answer and Explanation

The Correct Answer is B

Choice A rationale: Physical dependence is a state where the body has adapted to the presence of the opioid, and abrupt cessation may lead to withdrawal symptoms. However, the patient's statement indicates tolerance more than physical dependence.
Choice B rationale: The patient is at risk for tolerance, which is the need for an increased dose of a substance to achieve the same effect. This is common in chronic opioid therapy.
Choice C rationale: Abstinence syndrome is another term for withdrawal syndrome, and this is more associated with sudden cessation of opioids.

Correct Answer is A

Explanation

Choice A rationale: Before administering lithium, the nurse should assess serum creatinine levels. Lithium is excreted by the kidneys, and impaired renal function can lead to lithium toxicity.
Choice B rationale: Serum troponin I and T levels are markers of cardiac damage and are not directly related to lithium therapy.
Choice C rationale: Fasting blood glucose level is not specifically related to the assessment needed before administering lithium.
Choice D rationale: Serum lipid profile is not directly related to the assessment needed before administering lithium.

A. Increased speed of conduction and gluconeogenesis B. Bronchodilation and increased heart rate, contractility, and conduction C. Increased vasodilation and enhanced myocardial contractility D. Bronchoconstriction and increased heart rate

Correct Answer is B

Explanation

Choice A rationale: Epinephrine does increase the speed of conduction, but it does not significantly contribute to gluconeogenesis.
Choice B rationale: Epinephrine is used in cardiac arrest to increase heart rate, contractility, and conduction. In asthma, it causes bronchodilation.
Choice C rationale: While epinephrine can cause some vasodilation, it is not a primary indication for its use in cardiac arrest or status asthmaticus.
Choice D rationale: Epinephrine causes bronchodilation, not bronchoconstriction.
