Explanation:
(A) Although tumor size is a factor in classification of cancer growth, it is not an indicator of lymph node spread. (B) Axillary node status is the most important indicator for predicting how far the cancer has spread. If the lymph nodes are positive for cancer cells, the prognosis is poorer. (C) The client's previous history of cancer puts her at an increased risk for breast cancer recurrence, especially if the cancer occurred in the other breast. It does not predict prognosis, however. (D) The estrogen-progesterone assay test is used to identify present tumors being fedfrom an estrogen site within the body. Some breast cancers grow rapidly as long as there is an estrogen supply such as from the ovaries. The estrogen-progesterone assay test does not indicate the prognosis.

(A) When alcohol is ingested with disulfiram therapy, the client experiences nausea, vomiting, and a potentially serious drop in blood pressure. (B) Disulfiram is most successful when used early in the recovery process while the individual makes major lifestyle changes necessary for long-term recovery. (C) Disulfiram works on the classical conditioning principle. (D) The effects of disulfiram can be felt when alcohol is ingested 1-2 weeks after disulfiram is discontinued.

(A)
Catheter site care is to be done at least twice daily to prevent pathogen growth at the catheter insertion site. (B) Catheter drainage bags are usually emptied every 8 hours to prevent urine stasis and pathogen growth. (C) Tubing and collection bags are not changed this often, because research studies have not demonstrated the efficacy of this practice.
(D)
Fluid intake needs to be in the 2000-2500 mL range if possible to help irrigate the bladder and prevent infection.

Section: Questions Set E
Explanation:
(A) Bleeding is not a symptom of sickle cell anemia or sickle cell crisis. (B) Decreased blood viscosity leads to sickling of red blood cells. Increased fluid intake maintains adequate circulating blood volume and decreases the chance of sickling. (C) Hypoxia leads to sickling of cells. Flying in nonpressurized planes places the client in a situation of low O2 tension, which can lead to sickling. (D) Male and female clients with sickle cell disease can pass the trait on to their offspring. Therefore, this client should receive genetic counseling prior to having children.

Section: Questions Set B
Explanation:
(A) Both acorn squash and brussels sprouts are potassium-rich foods. (B) None of these foods is considered potassium rich. (C) Only the baked potato is a potassium-rich food. (D) Spinach is the only potassium-rich food in this option.
