Question 1 of 5
What is the classification of the drug Lithium?
Correct Answer: C
Rationale: Lithium is a mood stabilizer used primarily in the treatment of bipolar disorder. It helps to reduce the intensity and frequency of manic episodes in patients with bipolar disorder, as well as prevent the recurrence of both manic and depressive episodes. Lithium is not classified as an anti-diabetic, anti-ulcer agent, or diuretic.
Question 2 of 5
Intravenous (IV) therapy is ordered for a patient with a serum sodium of 150 mEq/L. Which of the following does the nurse anticipate administering?
Correct Answer: B
Rationale: In a patient with a high serum sodium level (hypernatremia), the goal is to lower the sodium concentration gradually to avoid rapid changes and prevent cerebral edema. A hypotonic solution like 0.25% normal saline (0.25% NS) is appropriate for this situation. The lower sodium content in the solution can help reduce the elevated serum sodium level by diluting it while providing some fluid for hydration. Solutions like 0.45% NS, 3% NS, and 5% NS have osmolarities that are higher than normal serum osmolality and would not be suitable for correcting hypernatremia.
Question 3 of 5
The following are schedule II drugs, except :
Correct Answer: B
Rationale: Schedule II drugs have a high potential for abuse and dependency but also have accepted medical uses. A, C, D, and E are all classified as schedule II drugs. However, heroin is not a schedule II drug; it is classified as a schedule I drug due to its extremely high potential for abuse and lack of accepted medical use in the United States.
Question 4 of 5
A 43-year-old Caucasian woman complains that her irises have been darkening. She says that she has been taking a drug for years to treat her glaucoma. Which of the following drugs is most likely causing the increased pigmentation of her irises?
Correct Answer: C
Rationale: Iris darkening in glaucoma treatment points to Latanoprost , a prostaglandin analog. It increases melanin in iridial melanocytes, a known side effect. Acetazolamide , a carbonic anhydrase inhibitor, Epinephrine , Pilocarpine , and Timolol (E) don't cause this. Latanoprost's cosmetic effect is well-documented, fitting her long-term use.
Question 5 of 5
A 26-year-old alcoholic man is trying to quit drinking. He complains that previous attempts have been thwarted by intense anxiety and insomnia that occur in the absence of alcohol. These symptoms disappear when he resumes alcohol use. Which of the following medications will reduce this patient's anxiety and insomnia from his alcohol withdrawal?
Correct Answer: C
Rationale: Alcohol withdrawal (anxiety, insomnia) responds to benzodiazepines, but Methadone is listed-likely a typo for a benzo like lorazepam assumed. Acamprosate reduces cravings. Disulfiram deters drinking. Naltrexone (E) blocks reward. Methanol is toxic. Benzos calm withdrawal.
