Answer and Explanation

The Correct Answer is C

A) pH 7.32, PaO2 88 mmHg, PaCO2 50 mmHg, HCO3 29 mEq/L, O2 sat 94%
This result suggests respiratory acidosis rather than respiratory alkalosis. In respiratory acidosis, the pH would be low (acidotic), PaCO2 would be elevated (since it reflects CO2 retention), and HCO3 would typically be elevated as a compensatory mechanism. This set of ABG values does not align with respiratory alkalosis, so it is not consistent with partially compensated respiratory alkalosis.

B) pH 7.35, PaO2 98 mmHg, PaCO2 55 mmHg, HCO3 28 mEq/L, O2 sat 99%
This set of values suggests respiratory acidosis, as indicated by a low pH (acidosis) and high PaCO2 (carbon dioxide retention). The HCO3 value is slightly elevated in compensation for respiratory acidosis, but this is not an example of partially compensated respiratory alkalosis, so it doesn't match the question's requirement.

C) pH 7.64, PaO2 94 mmHg, PaCO2 23 mmHg, HCO3 14 mEq/L, O2 sat 88%
This result is consistent with partially compensated respiratory alkalosis. In respiratory alkalosis, the pH would be elevated (alkalotic), PaCO2 would be low (indicating hyperventilation), and the kidneys would attempt to compensate by lowering bicarbonate (HCO3). In this case, the low PaCO2 (23 mmHg) and the low HCO3 (14 mEq/L) demonstrate partial compensation. The pH is also elevated at 7.64, which aligns with alkalosis. This is the correct answer for partially compensated respiratory alkalosis.

D) pH 7.50, PaO2 91 mmHg, PaCO2 52 mmHg, HCO3 30 mEq/L, O2 sat 96%
This result suggests respiratory acidosis with compensation. The elevated PaCO2 (52 mmHg) indicates CO2 retention, leading to acidosis, while the slightly elevated HCO3 (30 mEq/L) shows that the kidneys are compensating for the respiratory acidosis. The pH of 7.50 is slightly alkalotic, but it is more consistent with compensation for respiratory acidosis rather than respiratory alkalosis. Thus, this set of ABG values does not match the description of partially compensated respiratory alkalosis.

Correct Answer is C

Explanation

A) Assess for conjunctival bleeding
Conjunctival bleeding refers to blood in the white part of the eye (the conjunctiva), which is typically associated with trauma, infections, or certain blood disorders, but it is not a common cause of diplopia (double vision). Diplopia in multiple sclerosis (MS) is more often due to nerve damage affecting the eye muscles or the pathways controlling eye movement. Therefore, assessing for conjunctival bleeding is not a priority intervention for a client with diplopia related to MS.

B) Encourage the use of sunglasses when outside
While wearing sunglasses may help alleviate light sensitivity, which is a common symptom in individuals with MS, it is not the most appropriate intervention for treating diplopia itself. Diplopia is typically caused by issues with eye muscle control or coordination, often related to the central nervous system. Therefore, while sunglasses might provide comfort, they do not address the underlying cause of the double vision.

C) Alternate the use of an eye patch on each eye
Alternating the use of an eye patch on each eye is an effective intervention for managing diplopia, especially when the cause is related to misalignment or weakness of the eye muscles. The eye patch works by covering one eye at a time to prevent double vision. In MS, this technique can help reduce the visual disturbance and provide relief until further interventions (such as eye exercises or medications) can be considered. This approach is commonly used to manage diplopia caused by nerve involvement affecting ocular muscle function.

D) Apply cool compresses for pain relief
Cool compresses may provide relief for eye irritation or inflammation, but they are not typically used to treat diplopia. Diplopia in MS is more related to neuromuscular dysfunction or nerve damage, rather than acute inflammation or irritation of the eye. Therefore, while a cool compress may offer temporary relief for other symptoms, it is not a targeted solution for double vision in this context.

A. Call for the rapid response team and request a portable chest x-ray B. Turn the suction drainage system off and auscultate breath sounds C. Apply a sterile dressing and tape on three sides D. Notify the healthcare provider immediately.

Correct Answer is C

Explanation

A. Call for the rapid response team and request a portable chest x-ray: While it is important to call for help and obtain imaging if needed, the immediate action is to address the potential pneumothorax by sealing the wound. The rapid response team and chest x-ray are necessary for further assessment, but securing the wound is the priority in the moment.

B. Turn the suction drainage system off and auscultate breath sounds: Turning off the suction drainage system and auscultating breath sounds may be part of subsequent assessment and care, but these actions are secondary to stopping the entry of air into the pleural space. Auscultating breath sounds would be important after the chest tube is secured to assess for signs of pneumothorax or other complications, but it is not the first priority.

C. Apply a sterile dressing and tape on three sides: The first priority when a chest tube becomes accidentally dislodged is to seal the wound to prevent air from entering the pleural space, which could cause a pneumothorax (collapsed lung). The correct method to seal the chest tube insertion site is to apply a sterile dressing and tape it on three sides. This technique allows air to escape from the pleural space but prevents air from entering, creating a temporary "one-way valve" effect. This is crucial in stabilizing the patient until further medical intervention can be provided. The fourth side of the dressing is left open to allow for air to escape, which helps prevent a tension pneumothorax

D. Notify the healthcare provider immediately: While notifying the healthcare provider is important, securing the wound to prevent further air entry is the immediate priority. Notifying the provider can occur after the dressing is applied. Prompt action to stabilize the chest tube site is crucial to prevent further respiratory distress or complications.
