1. When teaching a client with a prescription for Cephalexin, which of the following instructions should the nurse include?

A. Take the medication with an antacid.
B. Avoid dairy products while taking this medication.
C. Expect your stools to turn black.
D. Complete the full course of medication.

Correct answer: D

Rationale: The correct instruction for a client prescribed with Cephalexin is to complete the full course of medication. This is crucial to ensure the infection is completely treated and to reduce the risk of antibiotic resistance. Choices A, B, and C are incorrect. Taking Cephalexin with an antacid is generally not recommended as it may reduce its effectiveness. While dairy products can interfere with certain antibiotics, they do not have a direct interaction with Cephalexin. Stools turning black is not an expected side effect of Cephalexin.

2. Which of the following drugs is associated with extreme photosensitivity as a reaction?

A. Digitalis
B. Niacin
C. Tetracycline
D. Fluoroquinolones

Correct answer: C

Rationale: Tetracycline is known to cause extreme photosensitivity reactions, making individuals more sensitive to sunlight and increasing the risk of severe sunburn. It is essential for patients taking tetracycline to protect themselves from excessive sun exposure to prevent adverse reactions.

3. Which of the following is NOT an opioid or NSAID?

A. Morphine
B. Ibuprofen
C. Hydromorphone
D. Acetaminophen

Correct answer: D

Rationale: Acetaminophen is the correct answer as it is not classified as an opioid or NSAID. Acetaminophen is considered a non-opioid analgesic, which means it works by a different mechanism than opioids and NSAIDs to relieve pain and reduce fever. Morphine, hydromorphone, and ibuprofen, on the other hand, are classified as opioids or NSAIDs. Morphine and hydromorphone are opioids, while ibuprofen is an NSAID (Nonsteroidal Anti-Inflammatory Drug), all of which work through different mechanisms compared to acetaminophen.

4. A client has difficulty swallowing medications and is prescribed enteric-coated aspirin PO once daily. The client asks if the medication can be crushed to make it easier to swallow. Which of the following responses should the nurse provide?

A. Crushing the medication might cause you to have a stomachache or indigestion.
B. Crushing the medication is a good idea, and I can mix it in some ice cream for you.
C. Crushing the medication would release all the medication at once, rather than over time.
D. Crushing is unsafe, as it destroys the ingredients in the medication.

Correct answer: A

Rationale: Crushing an enteric-coated medication can cause it to break down in the stomach instead of the intestines, potentially leading to gastrointestinal distress like stomachache or indigestion. It is important to take enteric-coated medications whole to ensure they are properly absorbed in the intestines and to prevent irritation to the stomach.

5. ACE Inhibitors are used in the treatment of all EXCEPT:

A. Hypertension
B. Heart Failure
C. Hypotension
D. Diabetic nephropathy

Correct answer: C

Rationale: ACE inhibitors are commonly used in the treatment of hypertension, heart failure, and diabetic nephropathy due to their ability to reduce blood pressure, improve heart function, and protect the kidneys. However, they are not indicated for hypotension as they can further lower blood pressure, worsening the condition. Therefore, the correct answer is C. Choice A, hypertension, is correct as ACE inhibitors are a first-line treatment for this condition. Choice B, heart failure, is also correct as ACE inhibitors help improve heart function in patients with heart failure. Choice D, diabetic nephropathy, is correct as ACE inhibitors can slow the progression of kidney damage in diabetic patients.
