Explanation:
(A) Priapism in the trauma client is due to the neurological dysfunction seen in spinal cord injury. Priapism is an abnormal erection of the penis; it may be accompanied by pain and tenderness. This may disappear as spinal cord edema is relieved. (B) Priapism is not associated with death. (C) Urinary retention, rather than incontinence, may occur. (D) Reproductive dysfunction may be a secondary problem.

(A) Increased CO2 will occur in both acute and chronic respiratory acidosis. (B) Hypoxia does not determine acid-base status. (C) Elevation of HCO3 is a compensatory mechanism in acidosis that occurs almost immediately, but it takes hours to show any effect and days to reach maximum compensation. Renal disease and diuretic therapy may impair the ability of the kidneys to compensate. (D) Base excess is a nonrespiratory contributor to acid-base balance. It would increase to compensate for acidosis.

(A) Clients with respiratory diseases are generally mouth breathers. Cleaning the oral cavity may improve the client's appetite, increase her feelings of well-being, and remove the taste and odor of sputum. (B) Milk causes thick sputum; therefore, milk products would not be beneficial for this client. (C) Exercise prior to a meal would require increased O2 consumption and most likely would decrease the client's ability to eat. (D) Clients with respiratory diseases need increased fluid to liquefy secretions.

Explanation:
(A) Within 12 hours of delivery, the fundus of the uterus rises to, or slightly above or below, the umbilicus.
Fundal height generally decreases 1 fingerbreadth, or 1 cm/day. (B) The uterus descends into the pelvic cavity at approximately 10-12 postpartal days and can no longer be palpated abdominally. (C) Within 12 hours of delivery, the fundus of the uterus rises to, or slightly above or below, the umbilicus. Fundal height generally decreases 1 fingerbreadth, or 1 cm/day. An enlarged uterus may indicate subinvolution or postpartal hemorrhage. (D) Immediately following delivery, the uterus lies midline, about midway between the umbilicus and the symphysis pubis.

Explanation:
(A) Tetany is seen with low calcium. (B) Low potassium causes dysrhythmias because potassium is responsible for cardiac muscle activity. (C) Numbness of extremities is seen with high potassium. (D) Headache is not associated with potassium excess or deficiency.
