A nurse is assessing a client who has postoperative atelectasis and is hypoxic. Which of the following manifestations should the nurse expect?

Lethargy

Bradycardia

Intercostal retractions

Bradypnea

Answer and Explanation

The Correct Answer is C

Intercostal retractions, or the inward movement of the chest wall between the ribs, are a sign of respiratory distress and hypoxia. They indicate increased work of breathing and reduced lung expansion, which are common in clients who have postoperative atelectasis. Atelectasis is a collapse of alveoli in a part of the lung, which impairs gas exchange and oxygenation.

a) Lethargy, or a state of reduced mental alertness and energy, is not a typical manifestation of hypoxia. It can be caused by other factors, such as pain, medication, infection, or electrolyte imbalance. Hypoxia usually causes restlessness, anxiety, or confusion.
b) Bradycardia, or a slow heart rate, is not a typical manifestation of hypoxia. It can be caused by other factors, such as medication, vagal stimulation, or heart block. Hypoxia usually causes tachycardia, or a fast heart rate, as the body tries to compensate for the low oxygen level.
d) Bradypnea, or a slow respiratory rate, is not a typical manifestation of hypoxia. It can be caused by other factors, such as medication, brain injury, or metabolic alkalosis. Hypoxia usually causes tachypnea, or a fast respiratory rate, as the body tries to increase oxygen intake and carbon dioxide elimination.

Correct Answer is B

Explanation

Answer: B

Rationale:

A) "Expect your sputum cultures to be negative after 6 months of therapy":

While sputum cultures may become negative after a period of effective therapy, it is not always guaranteed to happen within exactly 6 months. Tuberculosis (TB) treatment usually involves several months of medication, and sputum cultures are monitored periodically to assess treatment efficacy, not solely at the 6-month mark.

B) "Drink at least 8 ounces of water when you take the pyrazinamide tablet":

Drinking plenty of water with pyrazinamide is important to prevent dehydration and to help minimize potential side effects, such as hyperuricemia or gout. Adequate hydration can also aid in the effective elimination of the medication from the body, thus reducing the risk of adverse effects.

C) "Provide a sputum specimen every 2 weeks to the clinic for testing":

Sputum specimens are typically provided less frequently than every 2 weeks, usually monthly, to monitor the progress of TB treatment. Testing frequency may vary depending on the client's condition and the healthcare provider's recommendations.

D) "Take isoniazid with an antacid":

Isoniazid should not be taken with antacids, as antacids can interfere with the absorption of isoniazid. It is usually advised to take isoniazid on an empty stomach, and clients should be instructed to wait at least 1 hour after taking isoniazid before consuming antacids.

A. "I take this medication once a day in the evening." B. "I rinse my mouth after taking this medication." C. "I use a spacer device when I inhale this medication." D. "I take this medication when I get an asthma attack."

Correct Answer is A

Explanation

Montelukast is an oral leukotriene receptor antagonist that prevents inﬂammation and bronchoconstriction in asthma. It is taken once daily in the evening to prevent nocturnal symptoms and improve morning lung function.

"I rinse my mouth after taking this medication." This is not necessary, as montelukast is not associated with oral thrush or dysgeusia, unlike some inhaled corticosteroids.
"I use a spacer device when I inhale this medication." This is not applicable, as montelukast is not an inhaler, but a tablet or chewable form.
"I take this medication when I get an asthma attack." This is not appropriate, as montelukast is not a rescue medication, but a maintenance medication that should be taken regularly to prevent asthma exacerbations. A short-acting beta2 agonist such as albuterol should be used for acute relief of symptoms.
