Chapter 27

1. Which of the following statements accurately describes the role of antidiuretic hormone in the regulation of body fluids?  When antidiuretic hormone is present,
  A) The renal tubules become impermeable to water
  B) The renal tubules become permeable to water
  C) Urine output is increased and diluted
  D) The frequency of voiding increases
  Ans: B
  When antidiuretic hormone is present, the distal tubule of the nephron becomes more permeable to water.



2. The process of filtration begins at the
  A) Glomerulus
  B) Loop of Henle
  C) Bowman’s capsule
  D) Collecting ducts
  Ans: A
  The process of filtration begins at the glomerulus.



3. The passageways of the kidney permit the urine to flow to the bladder and
  A) Act as a valve that covers the junction between the ureters and the bladder
  B) Surround the Bowman’s capsule, which is where the formation of urine begins
  C) Selectively reabsorb or secrete substance to maintain fluids and electrolytes
  D) Control external sphincter of the urethra and permit the control of urination
  Ans: C
  The capillaries of the glomerulus are porous, and, as the blood passes through the glomerular capillariesRemember,me constituents of the blood are filtered out.



4. Which of the following statements is an appropriate nursing diagnosis for an 80-year-old patient with the diagnosis of congestive heart failure with symptoms of edema, orthopnea, and confusion?
  A) Extracellular volume excess related to heart failure as evidenced by edema and orthopnea
  B) Congestive heart failure related to edema
  C) Fluid volume excess related to loss of sodium and potassium
  D) Fluid volume deficit related to congestive heart failure as evidenced by shortness of breath
  Ans: A
  Extracellular volume excess is the state in which a person experiences an excess of vascular and interstitial fluid.



5. A young man has developed gastric esophageal reflux disease. He is treating it with antacids. Which acid-base imbalance is he at risk for developing?
  A) Respiratory alkalosis
  B) Metabolic alkalosis
  C) Respiratory acidosis
  D) Metabolic acidosis
  Ans: B
  Endocrine disorders and ingestion of large amounts of antacids cause metabolic alkalosis.



6. The nurse is reviewing the patient’s arterial blood gas results.  The test reveals a pH of 7.52, a PaO2 level of 49 mmHg and an HCO3 level of 28 mEq/L. The nurse suspects the patient is most likely experiencing which of the following conditions?
  A) Metabolic alkalosis
  B) Metabolic acidosis
  C) Respiratory acidosis
  D) Respiratory alkalosis
  Ans: A
  Metabolic alkalosis occurs when there is excessive loss of body acids or with unusual intake of alkaline substances. It can also occur in conjunction with an ECF deficit or potassium deficit (known as “contraction alkalosis”). Vomiting or vigorous nasogastric suction frequently causes metabolic alkalosis. Endocrine disorders and ingestion of large amounts of antacids are other causes. The loss of stomach acid or taking in of base causes H+ shifts in the blood, and pH increases.



7. When an 80-year-old patient who takes diuretics for management of hypertension informs the nurse she takes laxatives daily to promote bowel movements, the nurse assesses the patient for possible symptoms of
  A) Hypocalcemia
  B) Hypothyroidism
  C) Hypoglycemia
  D) Hypokalemia
  Ans: D
  The frequent use of laxatives and diuretics promotes the excretion of potassium and magnesium from the body, increasing the risk for fluid and electrolyte deficits.
