The nurse is caring for a client diagnosed with pneumonia. Which medication will the nurse administer for treatment of client's problem of ineffective airway clearance?

dextromethorphan 10 mg PO q 4 r

cromolyn MDI 2 puffs daily

guaifenesin 200 mg PO q 4 hr

methylprednisone 30 mg IV BID

Answer and Explanation

The Correct Answer is C

A. Dextromethorphan 10 mg PO q 4 hr: Dextromethorphan is a cough suppressant, and while it may be useful for controlling a dry, non-productive cough, it is not appropriate for ineffective airway clearance in pneumonia. In fact, suppressing the cough in pneumonia could prevent the patient from clearing mucus from the airways, exacerbating the problem. It is more appropriate for a client who has a dry cough without significant mucus production.

B. Cromolyn MDI 2 puffs daily: Cromolyn is a mast cell stabilizer used for the prevention of asthma and allergy symptoms, and it is not typically used for treating pneumonia or ineffective airway clearance. It works by preventing the release of inflammatory mediators in response to allergens, but it does not address the issue of clearing mucus in the airways during a bacterial infection like pneumonia.

C. Guaifenesin 200 mg PO q 4 hr: Guaifenesin is an expectorant that helps loosen and thin mucus in the airways, making it easier for the client to cough up and clear secretions. This is the most appropriate medication for addressing ineffective airway clearance in a client with pneumonia, as the goal is to facilitate the removal of mucus and improve respiratory function. Guaifenesin does not suppress the cough reflex but instead promotes productive coughing, which is essential for clearing the airways during a respiratory infection like pneumonia.

D. Methylprednisolone 30 mg IV BID: Methylprednisolone is a corticosteroid used to reduce inflammation and control severe allergic or inflammatory conditions. While corticosteroids may be used in certain cases of pneumonia (e.g., in cases of significant inflammation or an underlying condition like COPD), they are not the first-line treatment for ineffective airway clearance. The priority in this case is to promote mucus clearance, which is better addressed by guaifenesin.

Correct Answer is ["A","C","D","E"]

Explanation

A. "How long have you had the pain?"
Asking about the duration of the pain is crucial in assessing a myocardial infarction (MI). The length of time the pain has been occurring can help the nurse determine if the pain is acute or has been ongoing. For instance, chest pain lasting more than 20 minutes or worsening in intensity could indicate an MI. Knowing the timing of the pain also helps establish whether it may be related to acute coronary syndrome (ACS), which requires immediate intervention.

B. "Do you have a history of coronary artery disease?"
While it’s important to understand the patient’s medical history, this question is more secondary during the initial assessment of a client with chest pain. This information is valuable for understanding the risk of cardiovascular events, but it is not the immediate focus when assessing the current pain. The nurse should prioritize questions that address the current symptoms and the characteristics of the pain first.

C. "How would you describe your pain?"
This question is essential to help differentiate the chest pain associated with a myocardial infarction from other causes, such as musculoskeletal pain or gastrointestinal issues. MI pain is typically described as a crushing, pressure-like, or squeezing sensation. Identifying the quality of the pain helps establish whether it’s consistent with a cardiac event. Understanding the description of the pain also provides information about the intensity and potential for myocardial damage.

D. "What were you doing when the pain began?"
This is an important question because activity-related chest pain can help determine the potential cause of the pain. Pain associated with physical exertion or emotional stress may point to an MI or angina. On the other hand, pain unrelated to activity might suggest other causes such as gastrointestinal issues or musculoskeletal pain. Inquiring about the onset of the pain can also provide insight into whether it is associated with physical strain or acute coronary syndrome.

E. "Can you rate your pain on a 0-10 scale?"
Pain assessment using a numeric pain scale (0-10) helps the nurse gauge the severity of the pain and track changes over time. It’s important for determining whether the pain is severe enough to be consistent with an acute myocardial infarction or if it might resolve on its own. This information is vital in deciding the urgency of interventions and treatment decisions.

A. pH 7.36, Pa02 98 mmHg, PaCO2 27 mmHg, HCO3 16 mEq/L, 02 sat 99% B. pH 7.47, Pa02 91 mmHg, PaCO2 52 mmHg. HCO3 30 mEg/L, 02 sat 96% C. pH 7.45, P302 86 mmHg, PaCO2 56 mmHg, HCO3 28 mEg/L, 02 sat 94% D. PH 7.32, PaO2 88 mmHg. PaCO2 54 mmHg. HCO3 29 mEq/L. 02 sat 94%

Correct Answer is A

Explanation

A. pH 7.36, PaO2 98 mmHg, PaCO2 27 mmHg, HCO3 16 mEq/L, O2 sat 99%: This set of ABG results is consistent with fully compensated metabolic acidosis. pH 7.36: This is within the normal range (7.35-7.45), indicating that compensation has occurred, as the pH has returned to normal levels. PaCO2 27 mmHg: The PaCO2 is low, suggesting that the respiratory system has compensated for the metabolic acidosis by increasing ventilation to excrete CO2, thus reducing the acid load. HCO3 16 mEq/L: The bicarbonate level is low, which is consistent with metabolic acidosis as the primary disturbance. The PaO2 and O2 saturation are normal, indicating adequate oxygenation. Since the pH is within the normal range and the PaCO2 and HCO3 levels reflect the compensatory changes needed to correct the metabolic acidosis, this is a case of fully compensated metabolic acidosis.

B. pH 7.47, PaO2 91 mmHg, PaCO2 52 mmHg, HCO3 30 mEq/L, O2 sat 96%:

This result indicates alkalosis rather than acidosis. The pH is alkalotic (7.47), and PaCO2 is elevated (52 mmHg), which suggests respiratory acidosis as the primary disturbance. The HCO3 is also high (30 mEq/L), which is consistent with metabolic compensation for respiratory acidosis, not for metabolic acidosis. Therefore, this is not consistent with fully compensated metabolic acidosis.

C. pH 7.45, PaO2 86 mmHg, PaCO2 56 mmHg, HCO3 28 mEq/L, O2 sat 94%:

The pH is normal, but PaCO2 is elevated (56 mmHg), indicating respiratory acidosis rather than metabolic acidosis. The HCO3 is also elevated (28 mEq/L), which is consistent with compensation for respiratory acidosis, not metabolic acidosis. This result suggests respiratory acidosis with compensated metabolic alkalosis rather than metabolic acidosis.

D. pH 7.32, PaO2 88 mmHg, PaCO2 54 mmHg, HCO3 29 mEq/L, O2 sat 94%:

The pH of 7.32 indicates acidosis, but it is not within the normal range, so this is not fully compensated. The PaCO2 is elevated (54 mmHg), indicating respiratory acidosis, and the HCO3 is elevated (29 mEq/L), showing metabolic compensation. However, since the pH has not yet returned to normal (it remains acidotic), this is an example of partially compensated respiratory acidosis, not fully compensated metabolic acidosis.

respiratory acidosis, not fully compensated metabolic acidosis.
