1. Which lab value should be monitored in a patient on digoxin?

• A. Monitor potassium levels
• B. Monitor calcium levels
• C. Monitor digoxin levels
• D. Monitor sodium levels

Correct answer: C

Rationale: The correct answer is to monitor digoxin levels in a patient on digoxin. Digoxin is a medication commonly used to treat heart conditions, and monitoring its levels in the blood is crucial to ensure that the patient is within the therapeutic range and to prevent toxicity. Monitoring potassium levels (Choice A) is important due to the potential of digoxin-induced hypokalemia, but the primary focus should be on monitoring digoxin levels. Monitoring calcium levels (Choice B) and sodium levels (Choice D) are not directly related to digoxin therapy and are not the primary lab values of concern when administering digoxin.

2. A charge nurse is teaching a group of newly licensed nurses about the correct use of restraints. Which of the following should the nurse include in the teaching?

• A. Placing a belt restraint on a school-age child who has seizures.
• B. Securing wrist restraints to the bed rails for an adolescent.
• C. Applying elbow immobilizers to an infant receiving cleft lip injury.
• D. Keeping the side rails of a toddler's crib elevated.

Correct answer: D

Rationale: The correct answer is D. Keeping the side rails of a toddler's crib elevated is an appropriate use of restraints to prevent the child from falling, which is an essential safety measure. Placing a belt restraint on a school-age child with seizures (choice A) is not recommended as it can be dangerous during a seizure. Securing wrist restraints to the bed rails for an adolescent (choice B) may cause harm and should not be done routinely. Applying elbow immobilizers to an infant receiving a cleft lip injury (choice C) is not a standard practice for managing this condition and would not be appropriate.

3. A healthcare provider is reviewing laboratory results for a client who is receiving heparin therapy. Which of the following results indicates that the medication is effective?

• A. Platelets 250,000/mm³
• B. aPTT 60 seconds
• C. Hemoglobin 15 g/dL
• D. INR 1.5

Correct answer: B

Rationale: An aPTT of 60 seconds indicates that the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot and is used to monitor heparin therapy. A therapeutic range for aPTT during heparin therapy is usually 1.5 to 2 times the control value, which is around 25-35 seconds. Platelets, hemoglobin, and INR values are not direct indicators of the effectiveness of heparin therapy.

4. A nurse is providing teaching to a client who has mild persistent asthma and has been prescribed montelukast. Which of the following statements should the nurse include in the teaching?

• A. This medication can be used to help you during an acute asthma attack.
• B. This medication helps decrease swelling and mucus production.
• C. This medication should be taken before exercise.
• D. This medication should be taken daily in the evening.

Correct answer: D

Rationale: The correct answer is D. Montelukast should be taken daily in the evening for long-term control of asthma, rather than for immediate relief. Choice A is incorrect because montelukast is not used for acute asthma attacks. Choice B is incorrect as montelukast works by blocking leukotrienes, not by decreasing swelling and mucus production. Choice C is incorrect as montelukast is not specifically taken before exercise.

5. A nurse is reviewing the results of an arterial blood gas analysis of a client who has chronic obstructive pulmonary disease. Which of the following results should the nurse expect?

• A. PaO2 of 95 mm Hg
• B. PaCO2 of 55 mm Hg
• C. HCO3 of 24 mEq/L
• D. pH level of 7.35

Correct answer: B

Rationale: In chronic obstructive pulmonary disease, there is impaired gas exchange, leading to retention of carbon dioxide (CO2) and subsequent respiratory acidosis. A PaCO2 of 55 mm Hg is higher than the normal range (35-45 mm Hg) and is indicative of respiratory acidosis in COPD. Choices A, C, and D are not typically associated with COPD. PaO2 may be decreased, HCO3 may be elevated to compensate for acidosis, and pH may be lower than 7.35 due to respiratory acidosis in COPD.
