1. A nurse is caring for a 2-year-old child after corrective surgery for Tetralogy of Fallot. The mother reports that the child has suddenly begun seizing. The nurse recognizes this problem is probably due to

A. A cerebral vascular accident
B. Postoperative meningitis
C. Medication reaction
D. Metabolic alkalosis

Correct answer: A

Rationale: The correct answer is a cerebral vascular accident. Polycythemia occurs as a physiological reaction to chronic hypoxemia, which commonly occurs in clients with Tetralogy of Fallot. Polycythemia and the resultant increased viscosity of the blood increase the risk of thromboembolic events, including cerebrovascular accidents. Signs and symptoms of a cerebral vascular accident include sudden paralysis, altered speech, extreme irritability or fatigue, and seizures. Postoperative meningitis (choice B) is less likely in this scenario as the sudden onset of seizing is more indicative of a vascular event rather than an infection. Medication reaction (choice C) is not the most probable cause given the history provided. Metabolic alkalosis (choice D) is not associated with sudden seizing in this context.

2. A client is in her third month of her first pregnancy. During the interview, she tells the nurse that she has several sex partners and is unsure of the identity of the baby's father. Which of the following nursing interventions is a priority?

A. Counsel the woman to consent to HIV screening.
B. Perform tests for sexually transmitted diseases.
C. Discuss her high risk for cervical cancer.
D. Refer the client to a family planning clinic.

Correct answer: A

Rationale: In this scenario, the client's disclosure of having multiple sex partners and uncertainty about the baby's father indicates a potential high risk for HIV. Therefore, the priority nursing intervention is to counsel the woman to consent to HIV screening. Early detection of HIV is crucial for initiating timely treatment and improving outcomes. Choices B, C, and D are not the priority in this situation as HIV screening takes precedence over testing for other sexually transmitted diseases, discussing cervical cancer risk, or referring to a family planning clinic.

3. A client using an intraaural hearing aid experiences whistling after placement. What is the nurse's next action?

A. Try to reposition the hearing aid
B. Change the batteries
C. Remove the device and have it cleaned
D. Notify the physician that the hearing aid is not working

Correct answer: A

Rationale: An intraaural hearing aid, also known as an in-the-ear hearing aid, is placed in the ear canal. Whistling after placement indicates improper positioning of the device. The correct action for the nurse is to try repositioning the hearing aid to eliminate the whistling. Changing the batteries is not necessary for addressing whistling. Removing the device to clean it is not the immediate action needed for whistling. Notifying the physician is premature without attempting to reposition the hearing aid first.

4. Clinical manifestations of asthma include:

A. Decreased expiratory time
B. Increased peak expiratory flow
C. Increased use of accessory muscles
D. Increased oxygen saturation

Correct answer: C

Rationale: Clinical manifestations of asthma include increased use of accessory muscles, increased expiratory time, increased peak expiratory flow, and decreased oxygen saturation. Choice A, 'Decreased expiratory time,' is incorrect because asthma typically presents with increased expiratory time due to airway obstruction. Choice B, 'Increased peak expiratory flow,' is incorrect as asthma commonly leads to decreased peak expiratory flow due to airway constriction. Choice D, 'Increased oxygen saturation,' is incorrect because asthma exacerbations often result in decreased oxygen saturation levels.

5. The healthcare professional calculates the IV flow rate for a patient receiving an antibiotic. The patient is to receive 100mL of the antibiotic over 30 minutes. The IV infusion set has a drop factor of 10 drops per milliliter. How many drops per minute should the healthcare professional set the IV to deliver?

A. 11
B. 19
C. 26
D. 33

Correct answer: D

Rationale: To determine the drops per minute for the IV flow rate, you can use the formula: Drops Per Minute = (Milliliters to be infused x Drop Factor) / Time in Minutes. Substituting the given values, you get 100 mL x 10 drops/mL / 30 minutes = 33 drops per minute. Therefore, the correct answer is 33, as the healthcare professional should set the IV to deliver 33 drops per minute to infuse the antibiotic correctly. Choices A, B, and C are incorrect as they do not match the calculated drops per minute based on the provided values.
