A nurse is contributing to the plan of care for a client who has a pleural chest tube with a closed drainage system. Which of the following actions should the nurse recommend for the client's care?
Maintain 30 ml sterile water in the drainage collection chamber
Place the drainage device level with the tube insertion site
Keep system tubing connections taped together.
Empty the drainage collection chamber every 4 hr.
The Correct Answer is C
A. Maintain 30 ml sterile water in the drainage collection chamber: The sterile water is maintained in the water-seal chamber, not the drainage collection chamber. The water-seal chamber typically holds about 2 cm of water to create a one-way valve preventing air from entering the pleural space, not 30 mL in the drainage area.
B. Place the drainage device level with the tube insertion site: The drainage device should always be kept below the level of the chest tube insertion site to allow gravity to assist drainage and to prevent backflow of fluid or air into the pleural cavity, which could cause complications.
C. Keep system tubing connections taped together: Taping the system tubing connections securely helps maintain a closed system, preventing accidental disconnections that could lead to air leaks or loss of the negative pressure needed for proper lung re-expansion. This is essential for the effectiveness of chest tube management.
D. Empty the drainage collection chamber every 4 hr: The drainage collection chamber is not emptied routinely. Instead, it is replaced when full or according to facility protocol. Frequent opening of the system increases the risk of introducing infection or losing the closed negative-pressure system.

Correct Answer is ["A","E","F","G"]
Explanation
- Urine protein: The presence of 3+ proteinuria is a significant finding suggestive of preeclampsia. Protein in the urine indicates renal involvement due to endothelial dysfunction, which is a hallmark complication in hypertensive disorders of pregnancy and needs immediate attention.
- Respiratory rate: A respiratory rate of 16/min falls within the normal adult range of 12 to 20 breaths per minute. There is no evidence of respiratory distress, tachypnea, or bradypnea, so this finding does not suggest a prenatal complication.
- Gravida/parity: Although the client has a history of one preterm birth, gravida and parity alone are not indicators of a current prenatal complication. It is important background information but does not point directly to an acute complication at this time.
- Urine ketones: The absence of ketones in the urine is a normal finding. If ketones were present, it could suggest dehydration, starvation, or uncontrolled diabetes, but since they are negative, ketones are not a concern for prenatal complication here.
- Headache: A severe headache unrelieved by acetaminophen in a pregnant woman can signal worsening hypertension or preeclampsia. Persistent headaches are a concerning symptom that warrants immediate evaluation and management to prevent maternal and fetal harm.
- Fetal activity: Decreased fetal movement is a worrisome sign of possible fetal compromise, such as hypoxia or placental insufficiency. Reduced movements require further fetal assessment and monitoring to ensure fetal well-being.
- Blood pressure: A blood pressure reading of 162/112 mm Hg is severely elevated and meets the diagnostic criteria for severe preeclampsia. Uncontrolled hypertension during pregnancy places both the mother and fetus at significant risk for serious complications.
Correct Answer is B
Explanation
A. Hypertension: Clients experiencing diabetic ketoacidosis (DKA) are more likely to present with hypotension rather than hypertension due to dehydration caused by osmotic diuresis. Volume depletion significantly lowers blood pressure rather than raising it in the setting of DKA.
B. Fruity breath odor: A fruity or acetone-like breath odor is a hallmark sign of DKA. It results from the accumulation of ketones, particularly acetone, in the blood, which the body attempts to eliminate through the lungs, giving the breath its characteristic sweet or fruity smell.
C. Protruding eyeballs: Protruding eyeballs, or exophthalmos, are associated with hyperthyroidism, particularly Graves' disease, not with diabetic ketoacidosis. DKA affects metabolic and acid-base balance but does not cause changes to eye appearance or positioning.
D. Decreased urinary output: In the early stages of DKA, clients usually experience increased urinary output (polyuria) due to osmotic diuresis from hyperglycemia. Decreased output may occur only in the later stages when severe dehydration and kidney compromise develop, but it is not an early expected finding.
