The nurse prepares to administer lithium, a mood stabilizing drug, to a patient. Which laboratory result should first be assessed?

Serum creatinine

Serum troponin I and T levels

Fasting blood glucose level

Serum lipid profile

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is B

Explanation

Choice A rationale: Atropine is not primarily used to prevent anxiety. Its main use is to increase heart rate by blocking vagal effects on the heart.
Choice B rationale: Atropine is commonly used to prevent or treat bradycardia, particularly during anesthesia induction, when vagal stimulation can lead to significant slowing of the heart rate.
Choice C rationale: Dry mouth is a common side effect of atropine, not its primary use. Atropine is not given to prevent dry mouth.
Choice D rationale: Atropine is not used to prevent hypertension. Its primary cardiovascular effect is to increase heart rate.

A. Dopamine B. Epinephrine C. Norepinephrine D. Pseudoephedrine

Correct Answer is B

Explanation

Choice A rationale: Dopamine is not the appropriate medication for an allergic reaction. It is a neurotransmitter and is not used in the treatment of anaphylaxis.
Choice B rationale: Epinephrine is the first-line treatment for anaphylaxis, including severe difficulty breathing and swelling of the tongue. It acts quickly to reverse the symptoms of an allergic reaction.
Choice C rationale: Norepinephrine is not the medication of choice for an allergic reaction. It primarily acts as a vasoconstrictor and is used in conditions like septic shock.
Choice D rationale: Pseudoephedrine is a decongestant and is not the appropriate medication for treating an allergic reaction with respiratory distress.
