a patient has been prescribed iodoquinol yodoxin prior to administering iodoquinol yodoxin what assessment should the nurse make

ATI RN

Pathophysiology Final Exam

1. Prior to administering iodoquinol (Yodoxin), what assessment should the nurse make?

A. Assess for allergy to iodine.
B. Note the time the patient last ate.
C. Assess for skin eruptions.
D. Assess for ophthalmic symptoms.

Correct answer: A

Rationale: Before administering iodoquinol (Yodoxin), the nurse should assess for allergy to iodine since iodoquinol is a medication containing iodine. Assessing for skin eruptions (choice C) and ophthalmic symptoms (choice D) are not specifically related to iodoquinol administration. Noting the time the patient last ate (choice B) may be relevant for certain medications but is not directly related to assessing for an allergy to iodine in this case.

2. A client with cystic fibrosis is admitted with a pulmonary exacerbation. Which intervention should the nurse prioritize?

A. Administer a high-calorie, high-protein diet.
B. Initiate airway clearance techniques.
C. Encourage the client to maintain an active lifestyle.
D. Monitor for signs of respiratory distress.

Correct answer: B

Rationale: During a pulmonary exacerbation in cystic fibrosis, the priority intervention is to initiate airway clearance techniques. These techniques help clear mucus from the airways, improving ventilation and reducing the risk of respiratory complications. Administering a high-calorie, high-protein diet is beneficial for overall nutrition but is not the priority during an exacerbation. Encouraging an active lifestyle is important for long-term health but does not address the immediate need for managing exacerbations. Monitoring for signs of respiratory distress is important, but initiating airway clearance techniques takes precedence in the management of pulmonary exacerbations in cystic fibrosis.

3. A woman is complaining that she feels like the room is spinning even though she is not moving. Which of the following is characteristic of benign positional vertigo?

A. It usually occurs with a headache.
B. Pupillary changes are common.
C. It is usually triggered when the patient bends forward.
D. Nystagmus continues even when eyes fixate on an object.

Correct answer: C

Rationale: Benign positional vertigo is typically triggered by changes in head position, such as bending forward or turning over in bed. This change in position leads to brief episodes of vertigo, often associated with nystagmus, which is rapid, involuntary eye movements. Pupillary changes and headaches are not typical features of benign positional vertigo, making choices B and A incorrect. Nystagmus in benign positional vertigo usually stops when the eyes fixate on an object, so choice D is also incorrect.

4. Which of the following characterizes ductal carcinoma in situ?

A. It is less common than lobular carcinoma in situ.
B. Malignant cells have not invaded the stroma.
C. It is considered a cancer precursor.
D. Malignant cells have not invaded the stroma; it is considered a cancer precursor and has a higher risk for invasive cancer compared to lobular carcinoma in situ.

Correct answer: D

Rationale: The correct answer is that ductal carcinoma in situ is characterized by malignant cells that have not invaded the stroma, making it a cancer precursor with a higher risk for invasive cancer compared to lobular carcinoma in situ. Choice A is incorrect because ductal carcinoma in situ is more common than lobular carcinoma in situ. Choice B is incorrect as it only partially describes ductal carcinoma in situ without mentioning its potential for progression to invasive cancer. Choice C is incorrect because it does not capture the complete characteristics of ductal carcinoma in situ, which include the risk for invasive cancer.

5. What function does aldosterone serve in the body?

A. Aldosterone causes a release of sodium from the body, decreases fluid volume, and decreases blood pressure
B. Aldosterone causes a retention of sodium in the body, increases fluid volume, and increases blood pressure
C. Aldosterone causes a release of sodium from the body, increases fluid volume, and decreases blood pressure
D. Aldosterone enhances intracellular sodium production and lowers blood pressure

Correct answer: B

Rationale: Aldosterone functions by causing the retention of sodium in the body, which results in an increase in fluid volume and blood pressure. Choice A is incorrect because aldosterone actually promotes sodium retention rather than release. Choice C is incorrect as it states that aldosterone decreases fluid volume, which is not accurate. Choice D is incorrect because aldosterone does not enhance intracellular sodium production; instead, it primarily acts on sodium reabsorption in the kidneys.
