Correct Answer: C

Rationale: The healthcare provider should first assess the patient to determine if any harm has occurred as a result of the medication error. Checking the patient's condition takes precedence as it allows for immediate intervention if necessary. Notifying the provider (choice A) can come later once the patient's condition is assessed. Reporting to the risk manager (choice B) and completing an incident report (choice D) are important steps but should follow the initial assessment of the patient to ensure timely and appropriate actions are taken.

Correct Answer: C

Rationale: The correct task that the charge nurse should delegate to the LPN is to administer an oral antibiotic to a patient. LPNs are trained and permitted to administer medications orally under the supervision of a registered nurse. Initiating a care plan (Choice A) and completing an initial assessment (Choice D) are tasks that typically require higher-level nursing education and critical thinking skills, which are more suitable for registered nurses. Performing a complex wound dressing change (Choice B) involves specialized skills and assessment that are often within the scope of practice of registered nurses or wound care specialists.

Correct Answer: C

Rationale: The correct answer is C: Client's vaccination history. Before administering a pneumococcal vaccine, the nurse should verify the client's vaccination history to ensure they are due for the vaccine. Verifying the vaccination history helps prevent unnecessary vaccinations and ensures that the client receives the appropriate immunization at the right time. Choices A, B, and D are not directly related to the administration of the pneumococcal vaccine. Checking for allergies to eggs may be important for other vaccines, but it is not specifically relevant to pneumococcal vaccination. The client's current medications and blood pressure are important for general health assessment but are not directly related to verifying the need for a pneumococcal vaccine.

Correct Answer: A

Rationale: Corrected Rationale: Propranolol, a non-selective beta-blocker, should be avoided in clients with asthma as it can cause bronchoconstriction due to its beta2-blocking effects. Therefore, a client history finding of asthma would require the nurse to clarify this medication prescription. Hypertension, tachydysrhythmias, and urolithiasis are not contraindications for propranolol use, making them incorrect choices. For clients with asthma, a beta1 selective blocker would be preferred to avoid exacerbating bronchoconstriction.

Correct Answer: A

Rationale: A potassium level of 3.0 mEq/L indicates hypokalemia, which increases the risk of digoxin toxicity. In this case, the nurse should administer the digoxin without any modifications. Lowering the dose (Choice B) may not be necessary if the potassium level is not critically low. Monitoring serum potassium levels (Choice C) is important but should not delay the administration of digoxin. Discontinuing the medication (Choice D) is not the initial action to take unless the potassium levels become severely low and life-threatening.
