You should anticipate administering

Correct Answer: C

Rationale: Step-by-step rationale for why the correct answer is C: a diuretic. 1. Diuretics promote the excretion of excess water and salt from the body, reducing fluid volume in the bloodstream. 2. Administering a diuretic can help manage conditions like hypertension and heart failure by decreasing blood pressure and relieving edema. 3. Diuretics are commonly used to treat conditions where fluid retention is a concern. 4. In the given scenario, anticipating administering a diuretic would be appropriate to address potential fluid overload or edema. Summary: A: Analgesics are used for pain relief, not for addressing fluid retention or volume overload. B: Catecholamines are hormones involved in the body's fight-or-flight response and are not typically used to manage fluid balance. D: Nitroglycerin is a vasodilator used to treat angina and heart-related chest pain, not fluid retention issues.

Correct Answer: D

Rationale: The correct answer is D: Has a mitral valve stenosis. This is because Joan Timmerman presents with symptoms that may indicate a heart condition, such as shortness of breath and fatigue. Mitral valve stenosis is a condition where the heart's mitral valve is narrowed, leading to symptoms like fatigue and shortness of breath. Infectious mononucleosis (B) typically presents with symptoms like sore throat and swollen glands, not specifically related to Joan's symptoms. Emotionally upset (C) may cause fatigue but is less likely to cause shortness of breath. Being exhausted (A) is a general symptom and does not explain the specific symptoms Joan is experiencing.

Correct Answer: B

Rationale: The correct answer is B: Dopamine. Dopamine is a medication used in cases of shock, including cardiogenic shock from a myocardial infarction. It helps to increase blood pressure and heart rate, improving cardiac output. Atropine (A) is used for bradycardia, not shock. Digoxin (C) is used for heart failure, not shock. Adenosine (D) is used for certain types of arrhythmias, not shock. Dopamine is the most appropriate choice to counteract shock in cases of myocardial infarction.

Correct Answer: A

Rationale: The correct answer is A: Check the apical pulse for one minute. Before administering a beta blocker, it is essential to assess the client's heart rate as beta blockers can lower heart rate. Checking the apical pulse for one minute provides an accurate assessment of the client's baseline heart rate. This allows the nurse to identify any bradycardia or irregularities that may require the dose to be withheld or adjusted. Summary: B: Checking a potassium level is not directly related to the administration of a beta blocker. C: Checking a blood glucose level is not typically required before administering a beta blocker. D: Checking the pedal pulses is not as relevant as assessing the client's heart rate when administering a beta blocker.

Correct Answer: C

Rationale: The correct answer is C: Wolff-Parkinson White syndrome. This is because calcium channel blockers can exacerbate the accessory pathway in WPW syndrome, leading to potentially life-threatening arrhythmias. Choices A and B are not contraindications as calcium channel blockers are commonly used to manage hypertension and arrhythmias. Choice D, glaucoma, is not directly related to the use of calcium channel blockers for arrhythmias.
