The nurse is caring for a client with a nasogastric tube that is attached to low suction. If the client's HCO3- is 30, which additional value is most likely to be noted in this client?
- A. pH 7.52
- B. pH 7.36
- C. pH 7.25
- D. pH 7.20
Correct Answer: A
Rationale: Loss of gastric fluid via nasogastric suction or vomiting causes metabolic alkalosis because of the loss of hydrochloric acid (HCl), an acid secreted in the stomach. This occurs as HCO3 rises above normal. Thus, the loss of hydrogen ions in the HCl results in alkalosis. A pH above 7.45 would be noted.

The nurse provides discharge instructions to a client beginning oral hypoglycemic therapy. Which statements if made by the client indicate a need for further teaching? Select all that apply.
- A. If I am ill, I should skip my daily dose.
- B. If I overeat, I will double my dosage of medication.
- C. Oral agents are effective in managing type 2 diabetes.
- D. If I become pregnant, I will discontinue my medication.
- E. Oral hypoglycemic medications will cause my urine to turn orange.
- F. My medications are used to manage my diabetes along with diet and exercise.
Correct Answer: A,B,D,E
Rationale: Clients are instructed that oral agents are used in addition to diet and exercise as therapy for diabetes mellitus. During illness or periods of intense stress, the client should be instructed to monitor her or his blood glucose level frequently and should contact the primary health care provider if the blood glucose is elevated because insulin may be needed to prevent symptoms of acute hyperglycemia. The medication should not be skipped or the dosage should not be doubled. Taking extra medication should be avoided unless specifically prescribed by the primary health care provider. Medication should never be discontinued unless instructed to do so by the primary health care provider. However, the diabetic who becomes pregnant will need to contact her primary health care provider because the oral diabetic medication may have to be changed to insulin therapy because some oral hypoglycemics can be harmful to the fetus. These medications do not change the color of the urine.
Skin closure with heterograft will be performed on a client with a burn injury. When the client asks the nurse where the heterograft comes from, the nurse should explain it is from which source?
- A. A cadaver
- B. Another animal species
- C. The burned client themselves
- D. A man-made synthetic source
Correct Answer: B
Rationale: Biologic dressings are usually heterograft or homograft material. Heterograft is skin from another species. The most commonly used type of heterograft is pig skin because of its availability and its relative compatibility with human skin. Homograft is skin from another human, which is usually obtained from a cadaver and is provided through a skin bank. Autograft is skin from the client. Synthetic dressings are also available for covering burn wounds.
A postterm infant, delivered vaginally, is exhibiting tachypnea, grunting, retractions, and nasal flaring. The nurse interprets that these assessment findings are indicative of which condition?
- A. Hypoglycemia
- B. Respiratory distress syndrome
- C. Meconium aspiration syndrome
- D. Transient tachypnea of the newborn
Correct Answer: C
Rationale: Tachypnea, grunting, retractions, and nasal flaring are symptoms of respiratory distress related to meconium aspiration syndrome (MAS). MAS occurs often in postterm infants and develops when meconium in the amniotic fluid enters the lungs during fetal life or at birth. The symptoms noted in the question are unrelated to hypoglycemia. Respiratory distress syndrome is a complication of preterm infants. Transient tachypnea of the newborn is primarily found in infants delivered via cesarean section.
The nurse plans care for a client requiring intravenous (IV) fluids and electrolytes understanding that which are findings that correlate with the need for this type of therapy? Select all that apply.
- A. Hyponatremia
- B. Bounding pulse rate
- C. Chronic kidney disease
- D. Isolated syncope episodes
- E. Rapid, weak, and thready pulse
- F. Abnormal serum and urine osmolality levels
Correct Answer: A,E,F
Rationale: Abnormal assessment findings of major body systems offer clues to fluid and electrolyte imbalances. Rapid, weak, and thready pulse is an assessment abnormality found with fluid and electrolyte imbalances, such as hyponatremia. Abnormal serum and urine osmolality are laboratory tests that are helpful in identifying the presence of or risk of fluid imbalances. Isolated episodes of syncope are not indicators for intravenous therapy unless fluid and electrolyte imbalances are identified. A bounding pulse rate is a manifestation of fluid volume excess; therefore, IV fluids are not indicated. Clients with chronic kidney disease experience the inability of the kidneys to regulate the body's water balance; fluid restrictions may be used.
A client is scheduled to have a percutaneous transluminal coronary angioplasty (PTCA). What information about the balloon-tipped catheter should nurse plan to include when providing client education concerning the procedure?
- A. A mesh-like device within the catheter will be inflated causing it to spring open.
- B. The catheter will be used to compress the plaque against the coronary blood vessel wall.
- C. The catheter will cut away the plaque from the coronary vessel wall using an embedded blade.
- D. The catheter will be positioned in a coronary artery to take pressure measurements in the vessel.
Correct Answer: B
Rationale: In PTCA, a balloon-tipped catheter is used to compress the plaque against the coronary blood vessel wall. Option 1 describes placement of a coronary stent, option 3 describes coronary atherectomy, and option 4 describes part of the process used in cardiac catheterization.
