Explanation:
(A) Judicious use of analgesics is appropriate with breast engorgement; however, mechanical suppression would be the initial recommendation. (B) Breast-feeding every 11⁄2-3 hours will reduce and/or prevent breast engorgement. Breast-feeding will promote milk production, which will compound the distention and stasis of the venous circulation of engorgement in a bottlefeeding mother. (C) Ice packs reduce milk flow while the snug, supportive bra provides mechanical suppression and decreases pulling on Cooper's ligament. In addition, breast binders or ace bandages may be used for some women. (D) Warmth promotes milk production and may stimulate the let-down reflex. These measures would contribute to the venous congestion of engorgement.

Explanation:
(A) Anaerobic metabolism results because the decreased blood supply to the myocardium causes a release of lactic acid. Lactic acid is an irritant to the myocardial neural receptors, producing chest pain. (B) Chest pain is caused by a decrease in the O2 supply to the myocardial cells. Treatment modalities for chest pain are aimed toward increasing the blood flow through coronary arteries. (C) Chest pain causes an increase in the stimulation of the sympathetic nervous system. This stimulation increases the heart rate and blood pressure, causing an increase in myocardial workload aggravating the chest pain. (D) Chest pain and anxiety cause increased secretion of catecholamines by stimulating the sympathetic nervous system. This stimulation increases chest pain by increasing the workload of the heart.

(A) Uterine contractions increase with activity. (B) Walking will increase the strength and regularity of uterine contractions in true labor. (C) Uterine contractions that are strong and regular facilitate cervical dilation. (D) Regular, strong uterine contractions, as in true labor, result in fetal descent.

Explanation
(A) Cream cheese does not contain tyramine, which might cause a hypertensive crisis. (B) Fresh fruits do not contain tyramine, which might cause a hypertensive crisis. (C) Aged or matured cheese combined with a monoamine oxidase predisposes the client to a hypertensive crisis. (D) Bread products raised with yeast do not contain tyramine.

Explanation
(A) Hiccups are not a sign of impending hepatic coma. (B) Anorexia is not a sign of impending hepatic coma.
(C) One of the earliest symptoms of hepatic coma is mental confusion. Asterixis, a flapping tremor of the hand, may also be seen. (D) This sign is associated with the later stages of hepatic coma. Fetor hepaticus, a characteristic odor on the breath that smells like acetone, may sometimes be noted when the liver fails.
