Nursing Elites

1. The physician orders a Salem sump tube for gastrointestinal intubation. The nurse prepares for the insertion and obtains which of the following items from the supply room?

• A. A tube with a single lumen that connects to suction
• B. A tube with a large lumen and an air vent
• C. A Sengstaken-Blakemore tube
• D. A Dobbhoff weighted tube

Correct answer: B

Rationale: A tube with a large lumen and an air vent is a Salem sump tube. A tube with a single lumen is called a Levin’s tube. A Sengstaken-Blakemore tube is used to control bleeding in the esophagus. A Dobbhoff weighted tube is used for feedings.

2. Which of the following symptoms best describes Murphy’s sign?

• A. Periumbilical ecchymosis exists
• B. On deep palpation and release, pain is elicited
• C. On deep inspiration, pain is elicited and breathing stops
• D. Abdominal muscles are tightened in anticipation of palpation

Correct answer: C

Rationale: Murphy's sign is described as pain elicited on deep inspiration when the examiner's fingers are placed under the right costal margin.

3. The nurse has inserted a nasogastric tube to the level of the oropharynx and has repositioned the client’s head in a flexed-forward position. The client has been asked to begin swallowing. The nurse starts slowly to advance the nasogastric tube with each swallow. The client begins to cough, gag, and choke. Which nursing action would least likely result in proper tube insertion and promote client relaxation?

• A. Continuing to advance the tube to the desired distance
• B. Pulling the tube back slightly
• C. Checking the back of the pharynx using a tongue blade and flashlight.
• D. Instructing the client to breathe slowly and take sips of water.

Correct answer: A

Rationale: As the nasogastric tube is passed through the oropharynx, the gag reflex is stimulated, which may cause coughing, gagging, or choking. Instead of passing through to the esophagus, the nasogastric tube may coil around itself in the oropharynx, or it may enter the larynx and obstruct the airway, pulling the tube back slightly will remove it from the larynx; advancing the tube might position it in the trachea. Swallowing closes the epiglottis over the trachea and helps move the tube into the esophagus. Slow breathing helps the client relax to reduce the gag response. The nurse should check the back of the client’s throat to note if the tube has coiled. The tube may be advanced after the client relaxes.

4. The most important pathophysiologic factor contributing to the formation of esophageal varices is:

• A. Decreased prothrombin formation
• B. Decreased albumin formation by the liver
• C. Portal hypertension
• D. Increased central venous pressure

Correct answer: C

Rationale: Portal hypertension is the most important pathophysiologic factor contributing to the formation of esophageal varices.

5. The nurse is caring for a client with cirrhosis. Which manifestations indicate deficient vitamin K absorption caused by this liver disease?

• A. Dyspnea and fatigue
• B. Ascites and orthopnea
• C. Purpura and petechiae
• D. Gynecomastia and testicular atrophy

Correct answer: C

Rationale: A liver disorder, such as cirrhosis, can disrupt the liver's normal use of vitamin K to produce prothrombin (a clotting factor). Because of this, the nurse should monitor the client for signs of bleeding, including purpura and petechiae. Dyspnea and fatigue suggest anemia. Ascites and orthopnea are unrelated to vitamin K absorption. Gynecomastia and testicular atrophy result from decreased estrogen metabolism by the diseased liver.
