1. A client with an exacerbation of asthma is prescribed albuterol. The nurse should assess the client for which common side effect of this medication?
- A. Tremors
- B. Nausea and vomiting
- C. Insomnia
- D. Dry mouth
Correct answer: A
Rationale: The correct answer is A: Tremors. Albuterol, a beta-agonist medication commonly used to treat asthma exacerbations, can lead to tremors as a side effect. Tremors result from the stimulation of beta-2 receptors in muscles, particularly in the hands. Nausea and vomiting (Choice B) are generally not common side effects of albuterol. Insomnia (Choice C) is less likely to occur with albuterol, as it is a stimulant and can cause alertness rather than sleep disturbances. Dry mouth (Choice D) is not a typical side effect associated with albuterol use.
2. A client is experiencing preterm labor and has a prescription for 4 doses of dexamethasone 6 mg IM every 12 hours. The available concentration is dexamethasone 10 mg/mL. How many mL of dexamethasone should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use trailing zero.)
- A. 0.6 mL
- B. ---
- C. ---
- D. ---
Correct answer: A
Rationale: Calculation: (6 mg/dose) / (10 mg/mL) = 0.6 mL per dose. The correct answer is 0.6 mL. This calculation is obtained by dividing the dose needed (6 mg) by the concentration available (10 mg/mL). The resulting value is 0.6 mL per dose. Choices B, C, and D are not applicable as the correct answer has been calculated accurately.
3. A client admitted with shortness of breath and palpitations currently takes an antiarrhythmic medication, dronedarone. Which action should the nurse take to prevent arrhythmias?
- A. Measure orthostatic blood pressure
- B. Obtain a 12-lead ECG reading daily
- C. Assess the client's apical pulse daily
- D. Provide continuous ECG monitoring
Correct answer: D
Rationale: The correct action to prevent arrhythmias in a client taking an antiarrhythmic medication like dronedarone is to provide continuous ECG monitoring. This is essential because antiarrhythmic drugs can sometimes cause pro-arrhythmic effects, which may lead to dangerous heart rhythm disturbances. Continuous ECG monitoring allows for real-time detection of any abnormal rhythms, enabling prompt intervention. Measuring orthostatic blood pressure, obtaining a 12-lead ECG reading daily, and assessing the client's apical pulse daily are important assessments in general patient care but may not specifically prevent arrhythmias in this scenario.
4. A client with limited mobility in his lower extremities is being cared for by a nurse. Which of the following actions should the nurse take to prevent skin breakdown?
- A. Place the client in high-Fowler's position
- B. Increase the client's intake of carbohydrates
- C. Massage the reddened areas with unscented lotion
- D. Have the client use a trapeze bar when changing positions
Correct answer: D
Rationale: The correct answer is to have the client use a trapeze bar when changing positions. This action helps in repositioning without causing friction or shearing, which can lead to skin breakdown. Placing the client in high-Fowler's position (Choice A) may not directly prevent skin breakdown related to limited mobility. Increasing carbohydrate intake (Choice B) is not relevant to preventing skin breakdown. Massaging reddened areas with lotion (Choice C) can potentially cause more harm by increasing friction and damaging the skin further, rather than preventing breakdown.
5. A healthcare provider is assessing a newborn upon admission to the nursery. Which of the following should the provider expect?
- A. Bulging Fontanels
- B. Nasal Flaring
- C. Length from head to heel of 40 cm (15.7 in)
- D. Chest circumference 2 cm (0.8 in) smaller than the head circumference
Correct answer: D
Rationale: Upon admission to the nursery, a healthcare provider should expect the newborn's chest circumference to be slightly smaller than the head circumference. This is a normal finding in newborns due to their physiological development. Bulging fontanels (Choice A) can indicate increased intracranial pressure, which is abnormal. Nasal flaring (Choice B) is a sign of respiratory distress and is also an abnormal finding. While a length from head to heel of 40 cm (15.7 in) (Choice C) falls within the normal range for newborns, it is not a specific expectation upon admission to the nursery. Therefore, the correct expectation for a newborn upon admission is for the chest circumference to be slightly smaller than the head circumference.
