sleeping

Dehydration

Answer and Explanation

Correct Answer : A,C,E

Choice A rationale: Fever can cause an increase in metabolic rate which can lead to sinus tachycardia1.

Choice B rationale: Lisinopril is an ACE inhibitor used to treat hypertension, not a cause of sinus tachycardia1.

Choice C rationale: Albuterol is a bronchodilator that can cause sinus tachycardia as a side effect1.

Choice D rationale: Sleeping typically results in a slower heart rate, not sinus tachycardia1.

Choice E rationale: Dehydration can lead to low blood volume, causing the heart to beat faster to maintain blood pressure, resulting in sinus tachycardia1.
So, the correct answer is Choices A, C, and E, after analysing all choices.

Correct Answer is D

Explanation

Choice A rationale: The “ANALYZE” button is typically used to allow the defibrillator to analyze the heart rhythm. It would not ensure that the electricity is delivered on the R wave6.

Choice B rationale: The “SHOCK” button is used to deliver a shock during defibrillation or cardioversion. However, it does not specifically ensure that the shock is delivered on the R wave6.

Choice C rationale: The “ON” button is typically used to turn the device on or off. It does not control the timing of the electrical delivery6.

Choice D rationale: The “SYNC” button is used in synchronized cardioversion to match the delivery of the shock to the R wave of the ECG, which is the peak of the electrical wave during which the ventricular cells are depolarized6.

So, the correct answer is D, after analysing all choices.

A. "Heparin does not dissolve clots. It stops new clots from forming" B. "Heparin will begin dissolving clots over the next 24 hours C. "A pharmacist would be a better fit to answer that question. D. "It usually takes heparin at least 3 to 4 days to reach a therapeutic blood level."

Correct Answer is A

Explanation

Choice A rationale: Heparin is an anticoagulant that prevents new clots from forming but does not dissolve existing clots23.

Choice B rationale: Heparin does not directly dissolve clots23.

Choice C rationale: While a pharmacist can provide medication information, it is incorrect to say they would be a better fit to answer this question as nurses are trained in medication education23.

Choice D rationale: While it’s true that it takes time for heparin to reach a therapeutic blood level, this statement could be misleading because heparin does not dissolve clots23.

So, the correct answer is Choice A, after analysing all choices.
