The patient is being taught about pulmonary function testing (PFT). Which statement made by the patient indicates effective teaching?
- A. I will use my inhaler right before the test.
- B. I won't eat or drink anything 8 hours before the test.
- C. I should inhale deeply and blow out as hard as I can during the test.
- D. My blood pressure and pulse will be checked every 15 minutes after the test.
Correct Answer: C
Rationale: The correct answer is 'I should inhale deeply and blow out as hard as I can during the test.' This statement indicates effective teaching because for PFT, the patient needs to inhale deeply and exhale forcefully. This maneuver helps in assessing lung function accurately. Choices A, B, and D are incorrect. Using an inhaler right before the test may alter the test results, which is not recommended. Fasting for 8 hours is not necessary for a PFT, and checking blood pressure and pulse every 15 minutes after the test is not part of the PFT procedure.

A patient is scheduled for a computed tomography (CT) of the chest with contrast media. Which assessment finding should the nurse immediately report to the health care provider?
- A. Patient is claustrophobic.
- B. Patient is allergic to shellfish.
- C. Patient recently used a bronchodilator inhaler.
- D. Patient is not able to remove a wedding band.
Correct Answer: B
Rationale: The correct answer is that the patient is allergic to shellfish. This is crucial because the contrast media used in CT scans is iodine-based, and individuals with iodine allergies, such as those allergic to shellfish, are at risk of adverse reactions. It is important to identify and address this allergy to prevent potential complications. The other options do not directly impact the safety or effectiveness of the CT scan with contrast media. Claustrophobia can be managed with patient support, the recent use of a bronchodilator inhaler does not typically affect the CT procedure, and not being able to remove a wedding band is not a critical concern for the scan itself.
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.
Following assessment of a patient with pneumonia, the nurse identifies a nursing diagnosis of ineffective airway clearance. Which assessment data best supports this diagnosis?
- A. Weak, nonproductive cough effort
- B. Large amounts of greenish sputum
- C. Respiratory rate of 28 breaths/minute
- D. Resting pulse oximetry (SpO2) of 85%
Correct Answer: A
Rationale: The correct answer is 'Weak, nonproductive cough effort.' A weak, nonproductive cough indicates that the patient is unable to clear the airway effectively, supporting the nursing diagnosis of ineffective airway clearance. In pneumonia, secretions can obstruct the airway, leading to ineffective clearance. Choices B, C, and D do not directly reflect ineffective airway clearance. Large amounts of greenish sputum (Choice B) may suggest infection or inflammation but do not specifically indicate ineffective airway clearance. The respiratory rate of 28 breaths/minute (Choice C) and a resting pulse oximetry (SpO2) of 85% (Choice D) are more indicative of impaired gas exchange or respiratory distress rather than ineffective airway clearance.
Which of the following conditions is a contraindication for performing a diagnostic peritoneal lavage?
- A. A client who is 9 weeks pregnant
- B. A client with a femur fracture
- C. A morbidly obese client
- D. A client with hypertension
Correct Answer: C
Rationale: Diagnostic peritoneal lavage is contraindicated in morbidly obese clients due to several reasons. Excess body fat in morbidly obese individuals makes it challenging to locate essential landmarks required for the procedure. Additionally, the equipment utilized for the lavage may not be sized appropriately to accommodate an obese individual. Furthermore, morbid obesity places undue stress on the cardiovascular and respiratory systems, increasing the risk of complications when administering anesthetic agents during the procedure. Therefore, performing a diagnostic peritoneal lavage on a morbidly obese client is not recommended.
Choice A, a client who is 9 weeks pregnant, is not a contraindication for diagnostic peritoneal lavage. Pregnancy status alone does not preclude the procedure unless there are specific maternal or fetal concerns.
Choice B, a client with a femur fracture, is not a contraindication for diagnostic peritoneal lavage. The presence of a femur fracture does not typically affect the ability to perform this diagnostic procedure.
Choice D, a client with hypertension, is not a contraindication for diagnostic peritoneal lavage. Hypertension, while a consideration for anesthesia and surgery, does not directly impact the feasibility of performing a diagnostic peritoneal lavage.
While auscultating a patient's lungs, the nurse hears low-pitched, bubbling sounds during inhalation in the lower third of both lungs. How should the nurse document this finding?
- A. Inspiratory crackles at the bases
- B. Expiratory wheezes in both lungs
- C. Abnormal lung sounds in the apices of both lungs
- D. Pleural friction rub in the right and left lower lobes
Correct Answer: A
Rationale: The correct answer is 'Inspiratory crackles at the bases.' Crackles are low-pitched, bubbling sounds typically heard during inspiration, which aligns with the nurse's finding. Expiratory wheezes are high-pitched sounds and are not consistent with the described auscultation findings. The lower third of both lungs refers to the bases, not the apices, so option C is incorrect. Pleural friction rubs are grating sounds heard during both inspiration and expiration, unlike the described finding of only hearing the sounds during inhalation in the lower third of both lungs.
