Answer and Explanation

The Correct Answer is {"dropdown-group-1":"C","dropdown-group-2":"B"}

Rationale for Correct Choices:

  • N95 respirator. The client’s presentation of a cough, fatigue, night sweats, weight loss, and positive sputum culture for M. tuberculosis strongly suggests active tuberculosis (TB). Tuberculosis is transmitted through airborne particles, and an N95 respirator is required to protect healthcare workers from inhaling these particles. The N95 mask is specifically designed to filter out small particles, including the Mycobacterium tuberculosis bacteria.
  • Gloves. Gloves should be worn when caring for patients with suspected or confirmed TB to prevent contact transmission. While TB is primarily transmitted via airborne particles, gloves are still necessary to protect healthcare workers from coming into contact with bodily fluids such as sputum or any other potentially contaminated materials.

Rationale for Incorrect Options:

  • Face shield. A face shield is not required as primary protection for TB. While face shields can protect against splashes and droplets, TB is primarily transmitted via airborne particles, for which an N95 respirator is more appropriate.
  • Surgical mask. A surgical mask is not sufficient for protecting healthcare workers against tuberculosis because it does not filter out small airborne particles like the N95 respirator does. Surgical masks are primarily intended for droplet precautions, but tuberculosis is spread through airborne transmission, necessitating an N95 mask for adequate protection.
  • Gown. A gown is not required in this situation unless the patient has other symptoms or conditions that increase the risk of contamination, such as excessive wound drainage or the potential for body fluid splashes. For TB transmission, the primary concern is airborne transmission, and appropriate PPE focuses on respiratory protection (N95) and gloves for contact precautions.

Correct Answer is D

Explanation

A. Drain the tub water before the client gets out. Draining the tub water before the client gets out is not a recommended practice. Instead, the nurse should ensure that the client has a safe way to exit the tub while the water is still in it, as the water can provide support and stability when getting out.
B. Add bath oil to the water after the client gets into the tub. Adding bath oil to the water can create a slippery surface, increasing the risk of falls and injury. It is best to avoid bath oils, especially for clients who may have mobility issues or are at risk for falls.
C. Allow the client to remain in the bath for 30 min. While soaking in a tub can be relaxing, staying in the bath for too long can increase the risk of overheating or dehydration. A shorter duration may be more appropriate, depending on the client's condition and safety.
D. Check on the client every 10 min during the bath. Checking on the client regularly during the bath is essential for ensuring their safety. This practice allows the nurse to monitor for any signs of distress, difficulty, or the need for assistance, providing reassurance and promoting the client's well-being.

Correct Answer is A

Explanation

A. Positive Chvostek's sign. Hypocalcemia increases neuromuscular excitability, leading to involuntary twitching of facial muscles when the facial nerve is tapped. This sign is a well-known indicator of calcium deficiency and reflects heightened nerve sensitivity.
B. Hypotension. While severe hypocalcemia can affect cardiovascular function, hypotension is not a primary or consistent finding. More commonly, calcium imbalances affect muscle contractions rather than directly causing low blood pressure.
C. Confusion. Hypocalcemia can cause neurological symptoms, but confusion is more common in severe or prolonged cases. Early manifestations are usually neuromuscular, such as tetany or muscle cramps, rather than cognitive impairment.
D. Positive Babinski reflex. This reflex is associated with upper motor neuron dysfunction and neurological disorders rather than electrolyte imbalances like hypocalcemia. Calcium deficiency primarily affects peripheral nerves and muscle excitability.
