1. What does the PR interval on the ECG represent? What is the normal value?
The P-R interval is the interval between the beginning of electrical excitation of the atria and the beginning of excitation of the ventricles and its normal value is 0.12- 0.20 seconds.
2. What does the QRS complex on the ECG represent? What is implicit in the information that the QRS complexes on Mr. Ortega’s ECG had a normal configuration?
The QRS complex is the most important in the EKG since its represents depolarization (contraction) of Ventricles. A normal configuration QRS complex means the ventricular contraction is occurring normally with the spread of activation from the AV node through the bundle of His to the ventricular muscle.

Most dissolved substances in the blood plasma can easily move out of the bloodstream and into the interstitial fluid surrounding the cells. Will the nurse's mistake increase or decrease the "saltiness" of the interstitial fluid?
The nurse's mistake will increase 'saltiness' of the interstitial fluid. Sodium dissolves in plasma and is filtered into the interstitial fluid through capillary walls. As a result, the interstitial fluid will therefore increase.
6. What symptoms might result from hypernatremia?
Symptoms that might result from hypernatremia are weakness, nausea, confusion, thirst due to stimulation of the thirst center in the brain, difficulty in breathing due to pulmonary edema and muscle twitching.
7. How would this increase in salt load affect the patient's blood-aldosterone level? In your answer, explain the function of the hormone aldosterone.
The increase in salt load will cause the patient’s blood-aldosterone level to reduced aldosterone secretion. Aldosterone is a steroid hormone secreted by Zona glomerulosa of the adrenal cortex. It mostly bound to plasma proteins and its function is to facilitate increase of renal Na+ reabsorption and potassium
