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.

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.
A client diagnosed with left pleural effusion has just been admitted for treatment. The nurse should plan to have which procedure tray available for use at the bedside?
- A. Intubation
- B. Paracentesis
- C. Thoracentesis
- D. Central venous line insertion
Correct Answer: C
Rationale: The client with a significant pleural effusion is usually treated by thoracentesis. This procedure allows drainage of the fluid from the pleural space, which may then be analyzed to determine the precise cause of the effusion. The nurse ensures that a thoracentesis tray is readily available in case that the client's symptoms should rapidly become more severe. A paracentesis tray is needed for the removal of abdominal effusion. Options 1 and 4 are not specifically indicated for this procedure.
A client is brought to the emergency department reporting chest pain. Assessment shows vital signs that include a blood pressure (BP) of 150/90 mm Hg, pulse (P) 88 beats per minute (BPM), and respirations (R) 20 breaths per minute. The nurse administers nitroglycerin 0.4 mg sublingually. The treatment is found to be effective when the reassessment of vital signs shows which data?
- A. BP 150/90 mm Hg, P 70 BPM, R 24 breaths per minute
- B. BP 100/60 mm Hg, P 96 BPM, R 20 breaths per minute
- C. BP 100/60 mm Hg, P 70 BPM, R 24 breaths per minute
- D. BP 160/100 mm Hg, P 120 BPM, R 16 breaths per minute
Correct Answer: B
Rationale: Nitroglycerin dilates both arteries and veins, causing blood to pool in the periphery. This causes a reduced preload and therefore a drop in cardiac output. This vasodilation causes the blood pressure to fall. The drop in cardiac output causes the sympathetic nervous system to respond and attempt to maintain cardiac output by increasing the pulse. Beta blockers, such as propranolol, are often used in conjunction with nitroglycerin to prevent this rise in heart rate. If chest pain is reduced and cardiac workload is reduced, the client will be more comfortable; therefore, a rise in respirations should not be seen.
On assessment of a newborn being admitted to the nursery, the nurse palpates the anterior fontanel and notes that it feels soft. The nurse determines that this finding indicates which condition?
- A. Dehydration
- B. A normal finding
- C. Increased intracranial pressure
- D. Decreased intracranial pressure
Correct Answer: B
Rationale: The anterior fontanel is normally 2 to 3 cm in width, 3 to 4 cm in length, and diamond-like in shape. It can be described as soft, which is normal, or full and bulging, which could indicate increased intracranial pressure. Conversely a depressed fontanel could mean that the infant is dehydrated.
A client is diagnosed with cholecystitis. The nurse reviews the client's medical record, expecting to note documentation of which manifestations of this disorder? Select all that apply.
- A. Dyspepsia
- B. Dark stools
- C. Light-colored and clear urine
- D. Feelings of abdominal fullness
- E. Rebound tenderness in the abdomen
- F. Upper abdominal pain that radiates to the right shoulder
Correct Answer: A,D,E,F
Rationale: Cholecystitis is an inflammation of the gallbladder. Manifestations include dyspepsia; feelings of abdominal fullness; rebound tenderness (Blumberg's sign); upper abdominal pain or discomfort that can radiate to the right shoulder; pain triggered by a high-fat meal; clay-colored stools, dark urine, and possible steatorrhea; anorexia, nausea, and vomiting; eructation; flatulence; fever; and jaundice.
