CAT Exam Practice Test

1. Identify the placement of the stapes footplate into the bony labyrinth.

Correct answer: A

Rationale: The correct answer is A: Fenestra vestibuli. The stapes footplate is placed into the fenestra vestibuli of the bony labyrinth. This structure is also known as the oval window and is located at the junction of the middle ear and inner ear. Choice B, Fenestra cochleae, is incorrect as this opening is also known as the round window and is located near the base of the cochlea. Choice C, Tympanic membrane, is incorrect as it is also known as the eardrum and separates the external ear from the middle ear. Choice D, Round window, is incorrect as it is the opening covered by the secondary tympanic membrane and is important for the dissipation of sound waves in the cochlea.

2. A client is admitted for an exacerbation of heart failure (HF) and is being treated with diuretics for fluid volume excess. In planning nursing care, which interventions should the nurse include? (Select all that apply)

Correct answer: B

Rationale: The correct interventions to include when a client with heart failure is being treated with diuretics for fluid volume excess are to observe for evidence of hypokalemia. Diuretics can lead to potassium loss, resulting in hypokalemia. Monitoring for this electrolyte imbalance is crucial. Encouraging oral fluid intake of 3,000 ml/day may exacerbate fluid volume excess in a client with heart failure. Teaching the client how to restrict dietary sodium is important in managing heart failure, but it is not directly related to the use of diuretics for fluid volume excess. Monitoring PTT, PT, and INR lab values is not typically associated with diuretic therapy for heart failure but rather with anticoagulant therapy.

3. The mother of a school-age child calls the school to ask when her daughter can return to school after treatment for Pediculosis capitis. What is the nurse’s best response?

Correct answer: D

Rationale: The correct answer is 'After the treatment kills all the live lice.' The child can return to school once all live lice are eliminated to prevent the spread of Pediculosis capitis. This is essential as live lice are highly contagious. Choices A, B, and C are incorrect. Waiting for the itching to stop or for an epidemic to subside does not ensure that all live lice are eradicated, which is crucial to prevent reinfestation and transmission.

4. A client complains of paresthesia in the fingers and toes and experiences hand spasms when the blood pressure cuff is inflated. Which serum laboratory finding should the nurse expect to find when assessing the client?

Correct answer: C

Rationale: The correct answer is C: Low serum calcium. Hand spasms and paresthesia are indicative of potential hypocalcemia, which is characterized by low serum calcium levels. Elevated serum calcium (Choice A) is not consistent with the symptoms described. Low serum magnesium (Choice B) and elevated serum potassium (Choice D) are not typically associated with hand spasms and paresthesia.

5. A female client reports she has not had a bowel movement for 3 days, but now is defecating frequent small amounts of liquid stool. Which action should the nurse implement?

Correct answer: A

Rationale: The correct answer is A: Digitally check the client for a fecal impaction. Small, frequent liquid stools following constipation may indicate a fecal impaction. This intervention is crucial to assess and address a potential impaction promptly. Choices B, increasing fluid intake, and C, providing a high-fiber diet, may help with bowel regularity in general cases, but they don't directly address the urgent concern of a possible impaction. Choice D, administering a stool softener, is not appropriate as the first action when a fecal impaction is suspected; it could worsen the condition by causing further liquid stool output without addressing the impaction.
