A client has been prescribed vasopressin for the treatment of diabetes insipidus. What is the expected pharmacologic action of this medication?

A. To stimulate the pancreas to secrete insulin

B. To slow the absorption of glucose in the intestine

C. To increase reabsorption of water in the renal tubules

D. To increase blood pressure

Correct Answer: C
Rationale: The correct answer is C: To increase reabsorption of water in the renal tubules. Vasopressin, also known as antidiuretic hormone (ADH), works by increasing the reabsorption of water in the renal tubules, which helps to concentrate urine and reduce excessive urination in diabetes insipidus. Choice A is incorrect as vasopressin does not stimulate the pancreas to secrete insulin. Choice B is incorrect as vasopressin does not affect the absorption of glucose in the intestine. Choice D is incorrect as vasopressin's primary action is not to increase blood pressure, although it can have some vasoconstrictive effects.

A healthcare provider is reviewing the client's history before administering opioid pain medication. Which of the following conditions is a contraindication to opioid therapy?

• A. Asthma
• B. Renal failure
• C. Diabetes mellitus
• D. Obesity

Correct Answer: B
Rationale: Renal failure is a contraindication to opioid therapy due to the risk of drug accumulation and toxicity. Asthma, diabetes mellitus, and obesity are not contraindications to opioid therapy. Asthma is a respiratory condition that can be managed alongside opioids, diabetes mellitus and obesity do not directly contraindicate opioid therapy.

A nurse is caring for a client taking ciprofloxacin for an infection. Which of the following adverse effects should the nurse include in the client education?

• A. Constipation
• B. Tendon rupture
• C. Dry mouth
• D. Nasal congestion

Correct Answer: B
Rationale: The correct answer is B: Tendon rupture. Ciprofloxacin belongs to the fluoroquinolone class of antibiotics, which is associated with the adverse effect of tendon rupture. Tendon rupture is a severe but rare side effect that can occur with the use of ciprofloxacin. Educating the client about this potential adverse effect is crucial to promote awareness and early recognition of symptoms, such as tendon pain, swelling, or inflammation. Choices A, C, and D are not typically associated with ciprofloxacin use and are less relevant for client education in this scenario.

A client prescribed hydromorphone for severe pain has a decreased respiratory rate from 16 breaths per minute to 6. Which of the following medications should the nurse prepare to administer?

• A. Flumazenil
• B. Naloxone
• C. Activated charcoal
• D. Aluminum hydroxide

Correct Answer: B
Rationale: Naloxone is the correct answer as it is used to reverse opioid-induced respiratory depression. Hydromorphone is an opioid medication that can cause respiratory depression at high doses. Naloxone is an opioid antagonist that competes with opioids at receptor sites, reversing the effects of opioids like hydromorphone. Flumazenil (Choice A) is a benzodiazepine antagonist used for benzodiazepine overdose, not opioid overdose. Activated charcoal (Choice C) is used for toxin ingestion to prevent absorption in the gastrointestinal tract, but it is not indicated for opioid overdose. Aluminum hydroxide (Choice D) is an antacid and would not be the appropriate intervention for respiratory depression caused by opioid overdose.

A nurse is preparing to administer an intramuscular injection to an adult client. At what angle should the nurse administer the medication using the ventrogluteal site?

• A. a 45-degree angle
• B. a 60-degree angle
• C. a 75-degree angle
• D. a 90-degree angle

Correct Answer: D
Rationale: Intramuscular injections in the ventrogluteal site should be administered at a 90-degree angle. This angle ensures that the medication reaches the muscle tissue effectively. Angles less than 90 degrees can cause subcutaneous injection instead of intramuscular, leading to slower absorption of the medication. Angles greater than 90 degrees risk hitting bone or nerves, causing unnecessary pain or injury. Therefore, the correct angle for administering intramuscular injections in the ventrogluteal site is 90 degrees.
