The nurse caring for a 5-year-old with a history of tetralogy of Fallot notes that the child has clubbed fingers. This finding is indicative of which associated condition?
- A. Tissue hypoxia
- B. Chronic hypertension
- C. Delayed physical growth
- D. Destruction of bone marrow
Correct Answer: A
Rationale: Clubbing, a thickening and flattening of the tips of the fingers and toes, is thought to occur because of chronic tissue hypoxia and polycythemia. Options 2, 3, and 4 do not cause clubbing.

The nurse is preparing to administer an opioid to a client via an epidural catheter. Before administering the medication, the nurse aspirates and obtains 5 mL of clear fluid. Based on this finding, which action should the nurse take?
- A. Inject the opioid slowly.
- B. Notify the anesthesiologist.
- C. Inject the aspirate back into the catheter and administer the opioid.
- D. Flush the catheter with 6 mL of sterile water before injecting the opioid.
Correct Answer: B
Rationale: Aspiration of clear fluid of less than 1 mL is indicative of epidural catheter placement. More than 1 mL of clear fluid or bloody return means that the catheter may be in the subarachnoid space or a vessel. Therefore, the nurse would not inject the medication and would notify the anesthesiologist. Options 1, 3, and 4 are incorrect actions.
A clinic nurse is assessing a prenatal client who has been diagnosed with heart disease. The nurse carefully assesses the client's vital signs, weight, and fluid and nutritional status to detect for complications caused by which pregnancy-related concern?
- A. Rh incompatibility
- B. Fetal cardiomegaly
- C. The increase in circulating blood volume
- D. Hypertrophy and increased contractility of the heart
Correct Answer: C
Rationale: Pregnancy taxes the circulating system of every woman because the blood volume increases, which causes the cardiac output to increase. Stroke volume × heart rate = cardiac output (SV × HR = CO). Options 1, 2, and 4 are not directly associated with pregnancy in a client with a cardiac condition.
A newborn infant is diagnosed with esophageal atresia. Which assessment finding supports this diagnosis?
- A. Slowed reflexes
- B. Continuous drooling
- C. Diaphragmatic breathing
- D. Passage of large amounts of frothy stool
Correct Answer: B
Rationale: In esophageal atresia, the esophagus terminates before it reaches the stomach, ending in a blind pouch. This condition prevents the passage of swallowed mucus and saliva into the stomach. After fluid has accumulated in the pouch, it flows from the mouth and the infant then drools continuously. Responsiveness of the infant to stimulus would depend on the overall condition of the infant and is not considered a classic sign of esophageal atresia. Diaphragmatic breathing is not associated with this disorder. The inability to swallow amniotic fluid in utero prevents the accumulation of normal meconium, and lack of stools results.
A client diagnosed with myxedema reports having experienced a lack of energy, cold intolerance, and puffiness around the eyes and face. The nurse plans care knowing that these clinical manifestations are caused by a lack of production of which hormones? Select all that apply.
- A. Thyroxine (T4)
- B. Prolactin (PRL)
- C. Triiodothyronine (T3)
- D. Growth hormone (GH)
- E. Luteinizing hormone (LH)
- F. Adrenocorticotropic hormone (ACTH)
Correct Answer: A,C
Rationale: Although all of these hormones originate from the anterior pituitary, only T3 and T4 are associated with the client's symptoms. Myxedema results from inadequate thyroid hormone levels (T3 and T4). Low levels of thyroid hormone result in an overall decrease in the basal metabolic rate, affecting virtually every body system and leading to weakness, fatigue, and a decrease in heat production. A decrease in LH results in the loss of secondary sex characteristics. A decrease in ACTH is seen in Addison's disease. PRL stimulates breast milk production by the mammary glands, and GH affects bone and soft tissue by promoting growth through protein anabolism and lipolysis.
The nurse preparing to administer an intermittent tube feeding through a nasogastric (NG) tube assesses for residual volume. How do the resulting data assist in assuring the client's safety?
- A. Confirm proper NG tube placement.
- B. Determine the client's nutritional status.
- C. Evaluate the adequacy of gastric emptying.
- D. Assess the client's fluid and electrolyte status.
Correct Answer: C
Rationale: All stomach contents are aspirated and measured before administering a tube feeding to determine the gastric residual volume. If the stomach fails to empty and propel its contents forward, the tube feeding accumulates in the stomach and increases the client's risk of aspiration. If the aspirated gastric contents exceed the predetermined limit, the nurse withholds the tube feeding and collaborates with the primary health care provider on a plan of care. Assessing gastric residual volume does not confirm placement or assess fluid and electrolyte status. The nurse uses clinical indicators, including serum albumin levels, to determine the client's nutritional status.
