A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?
- A. Intercostal retractions
- B. Kussmaul respirations
- C. Low oxygen saturation (SpO2)
- D. Decreased venous O2 pressure
Correct Answer: B
Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.

A patient who was admitted the previous day with pneumonia complains of a sharp pain of 7 (based on a 0 to 10 scale) whenever taking a deep breath. Which action will the nurse take next?
- A. Auscultate breath sounds.
- B. Administer PRN morphine.
- C. Have the patient cough forcefully.
- D. Notify the patient's healthcare provider.
Correct Answer: A
Rationale: The patient's complaint of sharp pain when taking a deep breath is concerning for pleurisy or pleural effusion. The nurse should auscultate breath sounds to assess for a pleural friction rub or decreased breath sounds, which could indicate these conditions. It is crucial to gather assessment data before initiating any pain medications. Asking the patient to cough forcefully may exacerbate the pain and should be avoided until further assessment. Contacting the healthcare provider should be based on the assessment findings; therefore, it is premature to notify the provider without conducting a thorough assessment first.
When assessing a patient who has just arrived after an automobile accident, the emergency department nurse notes tachycardia and absent breath sounds over the right lung. For which intervention will the nurse prepare the patient?
- A. Emergency pericardiocentesis
- B. Stabilization of the chest wall with tape
- C. Administration of an inhaled bronchodilator
- D. Insertion of a chest tube with a chest drainage system
Correct Answer: D
Rationale: The patient's history and absent breath sounds suggest a right-sided pneumothorax or hemothorax, which will require treatment with a chest tube and drainage. Emergency pericardiocentesis is not indicated as the patient's symptoms are not suggestive of cardiac tamponade. Stabilization of the chest wall with tape would not address the underlying issue of a potential pneumothorax or hemothorax. Administration of an inhaled bronchodilator is not appropriate in this scenario as the patient is not exhibiting signs of asthma or bronchoconstriction. Therefore, the correct intervention for this patient is the insertion of a chest tube with a chest drainage system to address the potential pneumothorax or hemothorax.
A child is prescribed baclofen (Lioresal) via intrathecal pump to treat severe muscle spasms related to cerebral palsy. What teaching does the nurse provide the child and parents?
- A. Do not let this prescription run out.
- B. The medication may cause gingival hyperplasia.
- C. Periodic serum drug levels are needed.
- D. Watch for excessive facial hair growth.
Correct Answer: A
Rationale: The correct teaching for the child and parents when a child is prescribed baclofen via an intrathecal pump is to not let the prescription run out. Abrupt discontinuation of intrathecal baclofen can lead to severe effects like high fever, altered mental status, and rebound spasticity and muscle rigidity. It is crucial for the parents to ensure there is always an adequate supply of this medication to prevent these adverse effects. Choices B and D are incorrect because gingival hyperplasia and hirsutism are side effects associated with phenytoin (Dilantin), not baclofen. Choice C is incorrect as serum drug levels are not typically monitored for intrathecal medications.
A patient is admitted with active tuberculosis (TB). The nurse should question a healthcare provider's order to discontinue airborne precautions unless which assessment finding is documented?
- A. Chest x-ray shows no upper lobe infiltrates.
- B. TB medications have been taken for 6 months.
- C. Mantoux testing shows an induration of 10 mm.
- D. Three sputum smears for acid-fast bacilli are negative.
Correct Answer: D
Rationale: The correct answer is D: Three sputum smears for acid-fast bacilli are negative. Negative sputum smears indicate that Mycobacterium tuberculosis is not present in the sputum, and the patient cannot transmit the bacteria by the airborne route. This finding is crucial for discontinuing airborne precautions. Choice A is incorrect because chest x-rays do not determine the presence of active TB for transmission precautions. Choice B is not directly related to the infectiousness of TB; completing a 6-month course of medication is important for treatment but does not confirm the absence of active disease or infectiousness. Choice C is not relevant to assessing infectiousness; Mantoux testing measures exposure to TB but does not confirm the absence of active infection or infectiousness.
A patient with idiopathic pulmonary arterial hypertension (IPAH) is receiving nifedipine (Procardia). Which assessment would best indicate to the nurse that the patient's condition is improving?
- A. Blood pressure (BP) is less than 140/90 mm Hg.
- B. Patient reports decreased exertional dyspnea
- C. Heart rate is between 60 and 100 beats/minute
- D. Patient's chest x-ray indicates clear lung fields
Correct Answer: B
Rationale: The correct answer is for the patient to report decreased exertional dyspnea. In idiopathic pulmonary arterial hypertension (IPAH), exertional dyspnea is a significant symptom indicating disease severity. Improvement in this symptom suggests that the medication, nifedipine, is effective in managing the condition. While nifedipine can affect blood pressure (choice A) and heart rate (choice C), these parameters are not specific indicators for monitoring IPAH improvement. Choice D, clear lung fields on the chest x-ray, does not directly correlate with the effectiveness of therapy for IPAH. Therefore, the most relevant assessment to monitor improvement in a patient with IPAH receiving nifedipine is a decrease in exertional dyspnea.
