1. The healthcare professional is preparing to administer atenolol (Tenormin) to a client with angina. Which vital sign would cause the healthcare professional to question administering this drug?

A. Respirations 12 breaths per minute
B. Pulse 52 beats per minute
C. Blood pressure 134/72
D. Oxygen saturation 95%

Correct answer: B

Rationale: Atenolol is a beta-blocker medication that can lower heart rate. A pulse of 52 beats per minute is relatively low and administering atenolol could further decrease the heart rate, potentially leading to bradycardia. Monitoring the pulse rate and holding the medication if the pulse is below the prescribed parameters is crucial to prevent adverse effects such as bradycardia and hypotension.

2. A client has been prescribed a Beta Blocker for hypertension. Which of the following findings should the nurse monitor as an adverse effect of this medication?

A. Bradycardia
B. Hypertension
C. Hyperglycemia
D. Hypernatremia

Correct answer: A

Rationale: Bradycardia is the correct answer. Beta Blockers work by slowing down the heart rate, which can lead to bradycardia as an adverse effect. Monitoring for bradycardia is essential to prevent complications. Choices B, C, and D are incorrect because Beta Blockers do not typically cause hypertension, hyperglycemia, or hypernatremia as adverse effects.

3. A client is receiving treatment with carboplatin. Which of the following findings should the nurse monitor?

A. Hyperglycemia
B. Ototoxicity
C. Hypertension
D. Bradycardia

Correct answer: B

Rationale: Corrected Rationale: Carboplatin is known to cause ototoxicity as a serious adverse effect. It is essential for the nurse to monitor the client for any signs or symptoms of hearing loss or other auditory issues to address them promptly. Incorrect Choices Rationale: A) Hyperglycemia is not a common side effect associated with carboplatin. C) Hypertension is not a typical finding to monitor for specifically related to carboplatin treatment. D) Bradycardia is not a primary concern when monitoring a client on carboplatin.

4. What is the antidote for Warfarin?

A. Naloxone
B. Vitamin K
C. Glucagon
D. Vitamin B

Correct answer: B

Rationale: The correct antidote for Warfarin is Vitamin K. Warfarin works by inhibiting vitamin K-dependent clotting factors. Administering Vitamin K helps reverse its effects by replenishing these factors. Choices A, C, and D are incorrect. Naloxone is used to reverse opioid overdose, Glucagon is used to treat severe low blood sugar, and Vitamin B is not the antidote for Warfarin.

5. What is the therapeutic use of Phenytoin?

A. Replacement in hypothyroidism to restore normal hormonal balance
B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
C. Diminished seizure activity, termination of ventricular arrhythmias
D. Prevention of thrombus formation, prevention of extension of existing thrombi

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.
