Question 1 of 5
Which of the following signs might indicate a complication during the labor process with vertex presentation?
Correct Answer: D
Rationale: Fetal tachycardia may indicate fetal hypoxia; however, 170 bpm is only mild tachycardia. Nausea and vomiting occur frequently during transition and are not a complication. Contractions frequently last 60-90 seconds during the transitional phase of labor and are not considered a complication as long as the uterus relaxes completely between contractions. Passage of meconium in a vertex presentation is a sign of fetal distress; this may be normal in a breech presentation owing to pressure on the presenting part.
Question 2 of 5
A client develops an intestinal obstruction postoperatively. A nasogastric tube is attached to low, intermittent suction with orders to 'Irrigate NG tube with sterile saline q1h and prn.' The rationale for using sterile saline, as opposed to using sterile water to irrigate the NG tube is:
Correct Answer: A
Rationale: Water is a hypotonic solution and will deplete electrolytes and cause metabolic acidosis when used for nasogastric irrigation. Irrigating with saline does not cause abdominal discomfort. Severe, colicky abdominal pain is a symptom of intestinal obstruction. Irrigating with water will not cause restlessness or insomnia in the postoperative client. Restlessness and insomnia can be emotional complications of surgery. A nasogastric tube placed in the stomach is used to decompress the bowel. Irrigating with saline ensures a patent, well-functioning tube. Irrigating with saline will not increase peristalsis.
Question 3 of 5
A 55-year-old client is unconscious, and his physician has decided to begin tube feeding him using a small-bore silicone feeding tube (Keofeed, Duo-Tube). After the tube is inserted, the nurse identifies the most reliable way to confirm appropriate placement is to:
Correct Answer: C
Rationale: A chest x-ray is the most reliable method to confirm small-bore feeding tube placement, as other methods may be inconclusive or unreliable.
Question 4 of 5
Which task should be delegated to the licensed practical nurse?
Correct Answer: A, B, D, E
Rationale: LPNs can administer subcutaneous heparin (
A), feed via PEG tube (
B), monitor chest tubes (
D), and perform tracheostomy care (E). Removing a PICC line (
C) requires RN-level expertise due to potential complications.
Question 5 of 5
A child with croup is placed in a cool, high-humidity tent connected to room air. The primary purpose of the high-humidity tent is to:
Correct Answer: D
Rationale: High-humidity tents in croup moisten airways, liquefying secretions and relieving laryngeal spasms, easing breathing. Oxygen levels are not necessarily 30%, and dehydration or fever is secondary.
