- A. Severe chills
- B. Kernig's sign
- C. Brudzinski's sign
- D. Palpable hard thrombus

The manifestations of superficial thrombophlebitis include a palpable thrombus that feels bumpy and hard, tenderness and pain in the affected lower extremity, and a warm and pinkish red color over the thrombus area. Severe chills can occur in a variety of inflammatory or infectious conditions and are also a manifestation of pelvic thrombophlebitis.

The client states that he has smoked three-fourths of a pack per day over the last 10 years. The nurse calculates that the client has a smoking history of how many pack-years?
Correct Answer: 7.5
Rationale: The standard method for quantifying smoking history is to multiply the number of packs smoked per day by the number of years of smoking. The number is recorded as the number of pack-years. The calculation for the number of pack-years for the client who has smoked three-fourths of a pack per day for 10 years is 0.75 pack × 10 years = 7.5 pack-years.
The nurse is teaching the parents of a child diagnosed with celiac disease about dietary measures. The nurse should instruct the parents to take which measure?
- A. Restrict corn and rice in the diet.
- B. Restrict fresh vegetables in the diet.
- C. Substitute grain cereals with pasta products.
- D. Avoid foods that are hidden sources of gluten.
Correct Answer: D
Rationale: Gluten is found primarily in the grains of wheat, rye, barley, and oats. Gluten is added to many foods as hydrolyzed vegetable protein that is derived from cereal grains; therefore, labels need to be read. Corn and rice, as well as vegetables, are acceptable in a gluten-free diet, and corn and rice become substitute foods. Many pasta products contain gluten.
The nurse in the newborn nursery is planning for the admission of a large for gestational age (LGA) infant. In preparing to care for this infant, the nurse should obtain equipment to perform which diagnostic test?
- A. Serum insulin level
- B. Heel stick blood glucose
- C. Rh and ABO blood typing
- D. Indirect and direct bilirubin levels
Correct Answer: B
Rationale: After birth, the most common problem in the LGA infant is hypoglycemia, especially if the mother is diabetic. At delivery when the umbilical cord is clamped and cut, maternal blood glucose supply is lost. The newborn continues to produce large amounts of insulin, which depletes the infant's blood glucose within the first hours after birth.
The nurse assesses the water seal chamber of a closed chest drainage system and notes fluctuations in the chamber. What intervention should the nurse implement?
- A. Unkinking the tubing
- B. Assessing for an air leak
- C. Documenting that the lung has reexpanded
- D. Documenting that the lung has not yet reexpanded
Correct Answer: D
Rationale: Fluctuations (tidaling) in the water seal chamber are normal during inhalation and exhalation until the lung reexpands and the client no longer requires chest drainage. If fluctuations are absent, it could indicate occlusion of the tubing or that the lung has reexpanded. Excessive bubbling in the water seal chamber indicates that an air leak is present.
A client is scheduled for computed tomography (CT) of the kidneys to rule out renal disease. Which should the nurse assess the client for before the procedure to best assure the client's safety?
- A. Allergies
- B. Familial renal disease
- C. Frequent antibiotic use
- D. Long-term diuretic therapy
Correct Answer: A
Rationale: The client undergoing any type of diagnostic testing involving possible dye administration should be questioned about allergies, specifically an allergy to shellfish or iodine. This is essential to identify the risk for potential allergic reaction to contrast dye, which may be used.
