Correct Answer: C

Rationale: The correct answer is 'C: Bradycardia.' Atenolol, a beta-blocker, commonly causes bradycardia as an adverse effect. It works by slowing down the heart rate, which can lead to a decreased heart rate known as bradycardia. Monitoring for signs of bradycardia is essential to prevent any potential complications while on atenolol. Choices A, B, and D are incorrect because atenolol is not known to cause tachycardia, hypoglycemia, or hypertension as common adverse effects.

Correct Answer: B

Rationale: The correct instruction for taking Nitroglycerin is to take one tablet at the onset of chest pain, then repeat every 5 minutes for up to three doses. Option A is incorrect because taking a tablet every 15 minutes until pain is relieved may lead to delayed intervention. Option C is incorrect as taking Nitroglycerin at bedtime is not indicated for chest pain. Option D is incorrect as Nitroglycerin should be taken sublingually at the onset of chest pain, not on an empty stomach.

Correct Answer: D

Rationale: The correct answer is to monitor for signs of dehydration. Hydrochlorothiazide is a diuretic that can lead to fluid loss and dehydration. The client should be educated to watch for symptoms like dry mouth, increased thirst, weakness, dizziness, and decreased urine output. Prompt recognition of dehydration signs is crucial for timely intervention and prevention of complications. Choices A, B, and C are incorrect. Taking Hydrochlorothiazide in the morning is not a specific instruction for this medication. While potassium-rich foods can be important when taking certain medications, it is not the priority instruction for Hydrochlorothiazide. Taking this medication with food may help reduce stomach upset but is not the most critical instruction for a diuretic like Hydrochlorothiazide.

Correct Answer: C

Rationale: Muscle rigidity and a sudden rise in temperature are indicative of malignant hyperthermia, a potential complication of succinylcholine. Dantrolene is the drug of choice to treat malignant hyperthermia as it acts on skeletal muscles to reduce metabolic activity and counteract the symptoms. Neostigmine (Choice A) is used to reverse the effects of non-depolarizing neuromuscular blocking agents, not for malignant hyperthermia. Naloxone (Choice B) is an opioid antagonist used for opioid overdose. Vecuronium (Choice D) is a non-depolarizing neuromuscular blocking agent and is not the appropriate medication for malignant hyperthermia.

Correct Answer: A

Rationale: The correct instruction for the nurse to include when teaching a client with OCD who has a new prescription for Paroxetine is that it can take several weeks before the client feels like the medication is helping. Paroxetine, like other selective serotonin reuptake inhibitors (SSRIs), can take 1 to 4 weeks before the client reaches the full therapeutic benefit. Therefore, it is important to inform the client about this delay in onset of action to manage their expectations and promote adherence to the treatment plan. Choices B, C, and D are incorrect because taking Paroxetine before bedtime is not necessary, it should be taken consistently at the same time each day; Paroxetine is usually taken regularly, not as needed; and while monitoring weight is important, it is not a specific instruction related to the onset of action for Paroxetine.
