A client is to receive Synthroid 25 mcg PO daily. Synthroid unit dose available is 0.05 mg/ tablet. How many tablets (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)
The Correct Answer is ["0.5"]
Convert milligrams to micrograms.
1 mg = 1000 mcg.
0.05 mg × 1000 mcg/mg = 50 mcg
Desired dose = 25 mcg
Available dose = 50 mcg/tablet
Calculate the number of tablets.
Number of tablets = Desired dose / Available dose per tablet
= 25 mcg / 50 mcg/tablet
= 0.5
The nurse should administer 0.5 tablet.

Correct Answer is D
Explanation
A. Assist the client from the stretcher to a wheelchair: Immediately after electroconvulsive therapy (ECT), the client is still recovering from anesthesia and may experience confusion, drowsiness, or muscle weakness. Transferring the client prematurely poses a fall risk and is not appropriate as the first action.
B. Orient the client and offer reassurance: While reorientation and reassurance are important aspects of post-ECT care, safety and physiological stability must be assessed first. This action should follow an initial assessment of vital signs and level of consciousness.
C. Encourage the client to drink some fluids: Offering fluids too soon after ECT is inappropriate because the client may have impaired swallowing reflexes from anesthesia or sedation. Ensuring the airway is clear and the client is fully alert must precede oral intake.
D. Assess vital signs and orient client to the PACU environment: The priority after any procedure involving anesthesia is to assess vital signs to ensure hemodynamic stability and monitor for complications. Once stable, the nurse can begin to orient the client, which is often needed after ECT due to temporary disorientation or memory lapses.
Correct Answer is A
Explanation
A. Atrial fibrillation: Atrial fibrillation is characterized by an irregularly irregular rhythm, absence of identifiable P waves, and an unmeasurable PR interval. The ventricular rate can vary (in this case, 92/min), and QRS duration is usually normal. These findings match the classic ECG criteria for atrial fibrillation.
B. Sinus bradycardia: Sinus bradycardia features a regular rhythm, visible P waves before each QRS, and a rate below 60 bpm. The client's rate is 92 and the rhythm is irregular, ruling out this option.
C. Supraventricular tachycardia: SVT typically presents with a regular, rapid rhythm, often over 150 bpm, and P waves may be hidden in the preceding T wave. The client’s rate is 92 with an irregular rhythm, which does not fit SVT.
D. First-degree heart block: First-degree AV block is defined by a prolonged PR interval (>0.20 seconds) with otherwise normal sinus rhythm. In this case, the PR interval is unmeasurable and the rhythm is irregular, making this diagnosis unlikely.
