The nurse is conducting a staff in-service on appearance of childhood skin conditions. Lymphangitis ("streaking") is frequently seen in which condition?
- A. Cellulitis
- B. Folliculitis
- C. Impetigo contagiosa
- D. Staphylococcal scalded skin
Correct Answer: A
Rationale: Lymphangitis, characterized by "streaking" of red lines extending from the site of infection, is frequently seen in cellulitis. Cellulitis is a bacterial skin infection that affects the deeper layers of the skin and subcutaneous tissues. The red streaking in lymphangitis indicates an infection and inflammation of the lymphatic vessels, which are responsible for removing waste and fluids from the tissues. In cellulitis, bacteria enter the skin through a crack or break, leading to infection, inflammation, and the characteristic presentation of lymphangitis. This condition requires prompt medical attention and treatment with antibiotics to prevent further complications.
Mr. Garcia, a 41-year old chronic alcohol drinker is admitted to the hospital after vomiting bright red blood. He was diagnosed to have a bleeding gastric ulcer and suddenly develops sudden sharp pain in the midepigastric region with a rigid boardlike abdomen. This likely indicates:
- A. development of intestinal
- B. inflammation of the esophagus
- C. perforation of the ulcer
- D. development of additional ulcers
Correct Answer: C
Rationale: The sudden sharp pain in the midepigastric region with a rigid boardlike abdomen in a patient with a bleeding gastric ulcer, especially in the setting of chronic alcohol use, is indicative of a perforation of the ulcer. Perforation occurs when the ulcer penetrates through the wall of the stomach or duodenum, leading to the leakage of gastric contents into the peritoneal cavity. This results in peritonitis, causing severe abdominal pain and rigidity. Perforation of the ulcer is a surgical emergency requiring immediate intervention to repair the perforation, control the infection, and prevent further complications like sepsis. It is a life-threatening condition that necessitates prompt diagnosis and management.

Pulses can be graded according to certain criteria. Which is a description of a normal pulse?
- B. 1
- C. 2
- D. 3
Correct Answer: B
Rationale: In grading pulses, the normal pulse is typically designated as +1. This indicates a pulse that is easily felt, normal in strength, and corresponds to a healthy pulse rate. A +1 pulse is considered regular, not too weak or too strong, and is indicative of good cardiovascular health. Any abnormalities in pulse strength or rate would be graded differently.
