A nurse is caring for a client who has a prescription for levothyroxine.
Which of the following laboratory tests should the nurse monitor?
Serum potassium
Triiodothyronine
Blood urea nitrogen
Prothrombin time
The Correct Answer is B
Explanation B.Triiodothyronine
Levothyroxine is a synthetic form of the thyroid hormone thyroxine (T4). It is converted to triiodothyronine (T3), the active form of the thyroid hormone, in the body. Monitoring the levels of triiodothyronine (T3) can help assess the effectiveness of levothyroxine therapy and ensure that the client's thyroid hormone levels are within the desired therapeutic range.
Serum potassium levels in (option A) should not be monitored because they are not directly affected by levothyroxine. However, imbalances in electrolytes can occur in some individuals with thyroid disorders. Electrolyte levels may be monitored, but it is not the primary focus of monitoring for levothyroxine therapy.
Blood urea nitrogen (BUN) in (option C) should not be monitored because it is a test used to assess kidney function and is not directly related to monitoring levothyroxine therapy.
Prothrombin time (PT) in (option D) should not be monitored because it is a test used to evaluate the clotting function of the blood and is not specifically related to monitoring levothyroxine therapy.

Correct Answer is B
Explanation
Explanation
B. Instruct the client to change positions frequently
Encouraging the client to move around, walk, change positions during labour can help relieve discomfort, promote optimal fetal positioning positions, or use a birthing ball can help alleviate pelvic pain and potentially facilitate the progress of labour.
Applying fundal pressure during contractions in (option A) is not necessary during the latent stage of labour. Fundal pressure is typically used in the active stage of labour to assist with the descent and positioning of the baby's head.
Telling the client to push during contractions in (option C) is not appropriate during the latent stage of labour. Pushing is typically reserved for the second stage of labour when the cervix is fully dilated.
Encouraging the client to soak in a hot bath in (option D) is not recommended during labour, particularly in the hospital setting. Immersion in hot water (e.g., a hot bath) can increase the risk of infection and is generally not recommended until after the birth of the baby
Correct Answer is C
Explanation
Correct answer: C
A.Opening the dampers of fireplaces: This instruction is not appropriate during an outdoor chemical disaster. Opening the dampers of fireplaces can allow contaminated air from outside to enter the home, increasing the exposure to hazardous substances. It is best to avoid introducing outdoor air into the home during such incidents.
B. Turning on ceiling fans and air conditioners: This instruction is also not recommended during an outdoor chemical disaster. Turning on fans and air conditioners can potentially circulate contaminated air within the home, leading to increased exposure. It is best to turn off fans and air conditioners during such incidents and focus on evacuating the area.
C. Covering heat registers with plastic and tape: Covering heat registers with plastic and tape would help seal off potential entry points for contaminated air, reducing the risk of indoor contamination.
D.In the case of a nearby outdoor chemical disaster, it is usually safer to stay indoors and seal the home rather than exit, as going outside could increase exposure to the harmful chemicals.
