A nurse is assisting with teaching a class about physical manifestations associated with the fight-or-flight response to stress.
Which of the following manifestations should the nurse include?

Decreased blood pressure.

Bronchial airway constriction.

Hypoglycemia.

Dilated pupils.

Answer and Explanation

The Correct Answer is D

This is because the fight-or-flight response activates the sympathetic nervous system, which causes the pupils to dilate to allow more light and improve vision.

Choice A is wrong because the fight-or-flight response increases blood pressure by constricting blood vessels and increasing heart rate.

Choice B is wrong because the fight-or-flight response causes bronchial airway dilation to allow more oxygen intake and facilitate breathing.

Choice C is wrong because the fight-or-flight response causes hyperglycemia by stimulating the release of glucose from the liver and muscles to provide energy.

Normal ranges for blood pressure are 90/60 mmHg to 120/80 mmHg, for blood glucose are 70 mg/dL to 100 mg/dL, and for pupil size are 2 mm to 6 mm.

Correct Answer is A

Explanation

This is because hypokalemia (low potassium level in the blood) can cause abnormal heart rhythms (arrhythmia) that can be life-threatening and require urgent medical attention. A cardiac monitor can help detect and treat any arrhythmia that may occur.

Choice B is wrong because administering a laxative can worsen hypokalemia by causing more potassium loss through the digestive tract. Laxative use is one of the possible causes of hypokalemia.

Choice C is wrong because placing the client on seizure precautions is not a priority intervention for hypokalemia. Seizures are not a common symptom of hypokalemia, although muscle weakness and cramps may occur.

Choice D is wrong because restricting high potassium foods is not a priority intervention for hypokalemia. In fact, increasing potassium intake through foods or supplements may be helpful in less serious cases of hypokalemia. However, this should be done according to the doctor’s recommendation and with careful monitoring of blood potassium levels.

Normal blood potassium levels for an adult range from 3.6 to 5.2 millimoles per liter (mmol/L). A very low potassium level (less than 2.5 mmol/L) can be life threatening.

A. Left lower quadrant. B. Left upper quadrant. C. Right upper quadrant. D. Right lower quadrant.

Correct Answer is D

Explanation

McBurney’s point is located one-third of the distance from the right anterior superior iliac spine to the umbilicus. This is where the base of the appendix is attached to the cecum, which is part of the large intestine. When the appendix becomes inflamed or infected, it causes pain in this area.

Choice A is wrong because the left lower quadrant is where the sigmoid colon and part of the small intestine are located.

These organs are not related to appendicitis.

Choice B is wrong because the left upper quadrant is where the stomach, spleen, and part of the pancreas are located.

These organs are also not related to appendicitis.

Choice C is wrong because the right upper quadrant is where the liver, gallbladder, and part of the small intestine are located. These organs can cause pain in this area if they have problems, but not appendicitis
