A 7-year-old child is brought to the ER at midnight by his mother after symptoms appeared abruptly. The nurse's initial assessment reveals a temperature of 104.5F (40.3C), difficulty swallowing, drooling, absence of a spontaneous cough, and agitation. These symptoms are indicative of which one of the following?
Correct Answer: C
Explanation (A) Clinical manifestations of acute tracheitis include a 2-3 day history of URI, croupy cough, stridor, purulent secretions, high fever. (B) Clinical manifestations of spasmodic croup include a history of URI, croupy cough, stridor, dyspnea, low-grade fever, and a slow progression. The age group most affected is 3 months to 3 years. (C) Three clinical observations have been found to be predictive of epiglottitis: the presence of drooling, absence of spontaneous cough, and agitation.Epiglottitis has a rapid onset that is accompanied by high fever and dysphagia. (D) Clinical manifestations of acute laryngotracheobronchitis (LTB) include slow onset with a history of URI, low-grade fever, stridor, brassy cough, and irritability.
Question 267
A 47-year-old client comes to the emergency department complaining of moderate flank, abdominal, and testicular pain with nausea of 4 hours' duration. After physical examination and obtaining the client's history, the physician suspects urethral obstruction by calculi. The nurse realizes that the physician will order which one of the following diagnostic studies to best confirm the diagnosis?
Correct Answer: C
Explanation (A) Cystoscopy is an endoscopic procedure that uses an instrument (a cystoscope) to visualize the internal bladder and ureter structures and to capture and remove an obstructing stone. (B) Kidney, ureter, bladder x-ray is used to outline gross structural changes in the kidneys, ureter, and bladder and will determine the general location of a stone. (C) An intravenous pyelogram with excretory urogram is used to visualize the kidneys, kidney pelvis, ureters, and bladder. This procedure is used specifically to determine whether urethral obstruction is partial or complete; it shows the exact location of the stone and dilation of the ureter above the stone. (D) Ureterolithotomy is a surgical procedure in which the ureter is incised and the stone is manually removed because the stone is unable to pass through the ureter independently.
Question 268
A 70-year-old client is almost finished receiving her second unit of packed red blood cells. The client, who weighs 80 lb, has started complaining of being short of breath and now has crackles in the bases of her lungs. After slowing or stopping the transfusion, the most appropriate initial nursing action would be to:
Correct Answer: A
Section: Questions Set C Explanation: (A) Raising the client's head and placing her feet in a dependent position is an independent nursing action that can be taken to decrease venous return and to reduce pulmonary congestion. (B) Notifying the physician is an appropriate action that should be taken after the client is positioned to maximize her respiratory status. (C) Placing the client on O2may be done with a physician's order or according to an institution's standing orders; however, other actions should be taken first. (D) Furosemide 20 mg IV push is an appropriate medication for the client, but it must be ordered by her physician.
Question 269
The nurse would need to monitor the serum glucose levels of a client receiving which of the following medications, owing to its effects on glycogenolysis and insulin release?
Correct Answer: D
Explanation (A) Norepinephrine's side effects are primarily related to safe, effective care environment and include decreased peripheral perfusion and bradycardia. (B) Dobutamine's side effects include increased heart rate and blood pressure, ventricular ectopy, nausea, and headache. (C) Propranolol's side effects include elevated blood urea nitrogen, serum transaminase, alkaline phosphatase, and lactic dehydrogenase. (D) Epinephrine increases serum glucose levels by increasing glycogenolysis and inhibiting insulin release. Prolonged use can elevate serum lactate levels, leading to metabolic acidosis, increased urinary catecholamines, false elevation of blood urea nitrogen, and decreased coagulation time.
Question 270
Hypoxia is the primary problem related to near-drowning victims. The first organ that sustains irreversible damage after submersion in water is the:
Correct Answer: B
(A) The kidney can survive after 30 minutes of water submersion. (B) The cerebral neurons sustain irreversible damage after 4-6 minutes of water submersion. (C) The heart can survive up to 30 minutes of water submersion. (D) The lungs can survive up to 30 minutes of water submersion.
