Nursing Elites

1. The healthcare provider prescribes atenolol 50 mg daily for a client with angina pectoris. Which finding should the nurse report to the healthcare provider before administering this medication?

• A. Irregular pulse.
• B. Tachycardia.
• C. Chest pain.
• D. Urinary frequency.

Correct answer: A

Rationale: The correct answer is A: Irregular pulse. An irregular pulse may indicate an arrhythmia, which could be exacerbated by atenolol, a beta-blocker used to treat angina pectoris. Atenolol works by slowing the heart rate, so if the patient already has an irregular pulse, it could worsen with the medication. Tachycardia (choice B) would actually be an expected finding in a patient with angina pectoris, and atenolol is used to help reduce the heart rate in such cases. Chest pain (choice C) is a symptom that atenolol is meant to alleviate, so it would not be a reason to withhold the medication. Urinary frequency (choice D) is not directly related to the administration of atenolol for angina pectoris and would not require immediate reporting to the healthcare provider.

2. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which clinical finding is most concerning?

• A. Serum glucose of 500 mg/dL
• B. Serum glucose of 600 mg/dL
• C. Serum potassium of 5.5 mEq/L
• D. Serum bicarbonate of 18 mEq/L

Correct answer: D

Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with DKA as it indicates metabolic acidosis, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis. A low serum bicarbonate level is a key indicator of this acid-base imbalance. Elevated serum glucose levels are expected in DKA but are managed through insulin therapy. Serum potassium levels can fluctuate in DKA due to insulin deficiency, but a value of 5.5 mEq/L is not as immediately concerning as metabolic acidosis. Therefore, the most critical finding in this scenario is the low serum bicarbonate level.

3. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?

• A. Low bioavailability
• B. Rapid onset of action
• C. Short half-life
• D. Narrow therapeutic index

Correct answer: D

Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.

4. A 26-year-old female client is admitted to the hospital for treatment of a simple goiter, and levothyroxine sodium (Synthroid) is prescribed. Which symptoms indicate to the nurse that the prescribed dosage is too high for this client?

• A. Palpitations and shortness of breath
• B. Bradycardia and constipation
• C. Lethargy and lack of appetite
• D. Muscle cramping and dry, flushed skin

Correct answer: A

Rationale: The correct answer is A. An overdose of thyroid preparation generally manifests symptoms of an agitated state such as tremors, palpitations, shortness of breath, tachycardia, increased appetite, agitation, sweating, and diarrhea. Palpitations and shortness of breath are signs of excessive thyroid medication. Choices B, C, and D are incorrect symptoms for a dosage that is too high. Bradycardia and constipation, lethargy and lack of appetite, muscle cramping and dry, flushed skin are more indicative of hypothyroidism or an insufficient dosage of levothyroxine.

5. An older male client with a history of diabetes mellitus, chronic gout, and osteoarthritis comes to the clinic with a bag of medication bottles. Which intervention should the nurse implement first?

• A. Identify pills in the bag
• B. Review the client's medication schedule
• C. Assess the client's symptoms
• D. Educate the client about proper medication usage

Correct answer: A

Rationale: The correct answer is to identify pills in the bag first. This is essential to ensure the client is taking the correct medications and to prevent any potential medication errors. Reviewing the client's medication schedule (choice B) can come after identifying the pills to cross-reference the medications. Assessing the client's symptoms (choice C) is important but should follow identifying the medications. Educating the client about proper medication usage (choice D) is crucial but should be done after confirming the medications in the bag.
