1. What does a QRS Complex represent in an ECG reading?

Correct answer: C

Rationale: The QRS Complex in an ECG reading represents ventricular depolarization, which is the process of the heart's ventricles preparing to contract by changing the electrical charge in the cell, hence choice 'C' is the correct answer. Choice 'A' is incorrect because atrial depolarization is represented by the P wave in an ECG reading, not the QRS Complex. Choice 'B' is incorrect as ventricular repolarization is depicted by the T wave, not the QRS Complex. Finally, choice 'D' is also incorrect because the QRS Complex is not the end of ventricular depolarization, but the process itself.

2. The nurse notes that the fall might also cause a possible head injury. The patient will be observed for signs of increased intracranial pressure which include:

Correct answer: C

Rationale: Periorbital edema is a sign of increased intracranial pressure. It is caused by fluid accumulation around the eyes due to compromised drainage. Narrowing of the pulse pressure is more indicative of shock than increased intracranial pressure. While vomiting can be a sign of increased intracranial pressure, it is not as specific as periorbital edema. A positive Kernig's sign is associated with meningitis, not increased intracranial pressure.

3. The nurse knows that the most common complication of Measles is: A Pneumonia and larynigotracheitis

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

4. A client newly diagnosed with hypertension is receiving teaching about the Mediterranean diet from a nurse. Which of the following statements by the client indicates a need for further teaching?

Correct answer: D

Rationale: The correct answer is D. Patients with hypertension should be advised to limit alcohol consumption, including wine, to help manage their blood pressure. Choices A, B, and C are all consistent with the Mediterranean diet and are appropriate for a client with hypertension. Reducing red meat intake, consuming dairy in moderate portions, and having fish regularly align with the principles of this heart-healthy eating pattern.

5. With which of the following should fluoride supplements never be taken?

Correct answer: C

Rationale: Fluoride supplements should never be taken with milk because the fluoride binds with the calcium in the milk, thereby reducing the effectiveness of the fluoride supplement. Other beverages like water, juice, or soda do not share this characteristic as they do not contain the same level of calcium as milk. The rationale behind choosing milk as the correct answer is that it hampers the effectiveness of fluoride supplements, whereas the other choices do not.
