Question 1 of 5

In the case of an intramuscular injection of a drug:

A. Rate of drug absorption is enhanced by exercise B. Rate of drug absorption is greater from the deltoid than the gluteus maximus C. If administered to the buttock should be in the upper outer quadrant D. Rate of drug absorption is enhanced by exercise

Correct Answer: D

Rationale: Exercise increases blood flow to muscles, enhancing absorption of intramuscularly injected drugs.

Question 2 of 5

The patient has been receiving escitalopram (Lexapro) for treatment of obsessive-compulsive disorder. Unknown to the nurse, the patient has also been self-medicating with St. John's wort. The patient comes to the office with symptoms of hyperthermia and diaphoresis. Which statement best describes the result of the nurse's assessment?

A. The patient is experiencing symptoms of St. John's wort toxicity, as the medication was most likely outdated B. The patient has contracted a viral infection. Escitalopram (Lexapro) and St. John's wort are safe to take together C. The patient has not been taking escitalopram (Lexapro) and is experiencing withdrawal D. The patient has combined two antidepressant medications and is experiencing serotonin syndrome

Correct Answer: D

Rationale: Escitalopram and St. John's wort, both serotonin boosters, risk serotonin syndrome-hyperthermia, diaphoresis-per pharmacology. St. John's toxicity alone (e.g., photosensitivity) doesn't fit. They're not safe together-interaction is known. Withdrawal lacks agitation context. Serotonin excess explains symptoms, a critical finding.

Question 3 of 5

Select all when taking Iron Supplements.

A. One hour before or 2 hours after meal B. Full glass of water/ juice C. No caffeine D. Carry identification card saying you are on Iron Supplements

Correct Answer: A

Rationale: A. It is recommended to take iron supplements one hour before or two hours after a meal because food can interfere with the absorption of iron. By taking it on an empty stomach or away from meals, the body can absorb the iron more effectively.

Question 4 of 5

A 6-year-old boy is brought to his primary care physician with a history of hay fever and asthma. He usually has two to three attacks per week. For symptom control, he uses an albuterol inhaler, but his parents would like to try something more. They would like him to take something that would lessen the amount of attacks he has. Although corticosteroids would probably work best for prophylaxis, they are contraindicated in children. He is instead given montelukast. How does montelukast work?

A. Blocks leukotriene receptors B. Blocks muscarinic acetylcholine receptors C. Inhibits COX-1 and COX-2 D. Inhibits COX-2 only

Correct Answer: A

Rationale: Montelukast prevents asthma attacks by blocking leukotriene receptors . Leukotrienes drive inflammation; montelukast reduces this, complementing albuterol's acute relief. Muscarinic blockade is ipratropium's action. COX inhibition (C, D) is NSAIDs'. Lipoxygenase inhibition (E) is zileuton's. Montelukast's specificity suits prophylaxis in this child.

Question 5 of 5

A patient who has been diagnosed with social anxiety disorder will begin taking venlafaxine(Effexor). The nurse who performs a medication and dietary history will be concerned about ingestion of which substance or drug?

A. Coffee B. Grapefruit juice C. Oral hypoglycemic drug D. St. John's wort

Correct Answer: D

Rationale: St. John's wort is an herbal supplement known to interact with many medications, including venlafaxine (Effexor). It can reduce the effectiveness of venlafaxine by increasing its metabolism and clearance from the body, potentially leading to decreased therapeutic effects. Therefore, patients taking venlafaxine for social anxiety disorder should be advised to avoid St. John's wort to prevent any negative interactions and ensure the medication works effectively. It is essential for the nurse to inquire about the use of St. John's wort during the medication and dietary history assessment to prevent such interactions.
