Question 496

A client was exhibiting signs of mania and was recently started on lithium carbonate. She has no known physical problems. A teaching plan for this client would include which of the following?

Correct Answer: A
Explanation/Reference:
Explanation:
(A) This answer is correct. A balanced diet with adequate salt intake is necessary. (B) This answer is incorrect. The client must drink six to eight full glasses of fluid per day (2000-3000 mL/day). (C) This answer is incorrect. The client should be instructed to avoid fluctuations of sodium intake. Diet should be balanced, with an adequate salt intake. (D) This answer is incorrect.

Which of the following blood gas parameters primarily reflects respiratory function?

Correct Answer: A
Section: Questions Set D
Explanation:
(A) The lungs are responsible for regulation of CO2, and this parameter primarily reflects respiratory function.
(B) CO2 content of the blood is an indirect measure of respiratory function. (C) HCO3 is a measure of kidney function only and is important in acid-base balance. (D) Base excess represents the excess of HCO3 and is not reflective of respiratory function.

Question 498

A 70-year-old client has pneumonia and has just had a respiratory arrest. He has just been intubated with an 8- mm endotracheal tube. During auscultation of his chest, breath sounds were found to be absent on the left side. The nurse identifies the most likely cause of this as:

Correct Answer: C
Explanation/Reference:
Explanation:
(A) Appropriate endotracheal tube sizes for adults range from 7.0-8.5 mm. (B) Pneumothorax could be indicated by an absence of breath sounds on the affected side. However, in a recently intubated client, the first priority would be to consider tube malposition. (C) During intubation, the right mainstem bronchus can be inadvertently entered if the endotracheal tube is inserted too far. Left mainstem bronchus intubation almost never occurs because of the angle of the left mainstem bronchus. (D) Breath sounds for someone with pneumonia may be decreased over the areas of consolidation. However, in a recently intubated client, the first priority would be to consider tube malposition.

Question 499

A client's transfusion of packed red blood cells has been infusing for 2 hours. She is complaining of a raised, itchy rash and shortness of breath. She is wheezing, anxious, and very restless. The nurse knows these assessment findings are congruent with:

Correct Answer: D
Explanation
(A) A hemolytic transfusion reaction would be characterized by fever, chills, chest pain, hypotension, and tachypnea. (B) Fever, chills, and headaches are indicative of a febrile transfusion reaction. (C) Circulatory overload is manifest by dyspnea, cough, and pulmonary crackles. (D) Urticaria, pruritus, wheezing, and anxiety are indicative of an allergic transfusion reaction.
insert code

Question 500

Respiratory function is altered in a 16-year-old asthmatic. Which of the following is the cause of this alteration?

Correct Answer: C
(A) Altered surfactant production is found in sudden infant death syndrome. (B) Paradoxical breathing occurs when a negative intrathoracic pressure is transmitted to the abdomen by a weakened, poorly functioning diaphragm. (C) Asthma is characterized by spasm and constriction of the airways resulting in increased resistance to airflow. (D) If the pulmonary tree is obstructed for any reason, inspired air has difficulty overcoming the resistance and getting out. The rate of respiration increases in order to compensate, thus increasing air exchange.
