A client has a right-sided chest tube with 50 cc of serosanguinous fluid in the collection chamber and air bubbles are collecting in the water seal chamber. What is the most appropriate action for the nurse to take at this time?

Correct Answer: C

Rationale: The water seal of a chest tube acts as a one-way valve. Air bubbles in the water seal indicate a leak between the client and the chamber. The nurse should briefly clamp the tube near the client's chest to locate the source of the leak. Once identified, the nurse should unclamp the tubing and notify the physician immediately. Choice A is incorrect because air bubbles in the water seal chamber are not a normal finding and indicate a leak. Choice B is incorrect as stripping the tubing could aggravate the issue and is not the initial appropriate action. Choice D is incorrect as it does not address the immediate need to locate and address the leak.

Correct Answer: D

Rationale: A client with a blood glucose level of 48 mg/dl is experiencing significant hypoglycemia, as manifested by confusion, balance difficulties, and slurred speech. The nurse should work to correct this situation as rapidly as possible. The first measure that can be performed quickly and will have fast results is to give the client something to eat or drink that contains glucose, such as 6 oz. of orange juice. Administering a bolus of D20W through the IV (Choice B) would be too aggressive and could lead to complications in this scenario. Administering regular insulin (Choice C) would further lower the blood glucose level, worsening the client's symptoms. Contacting the physician (Choice A) is important, but immediate intervention to raise the blood glucose level is crucial to address the client's hypoglycemia.

Correct Answer: C

Rationale: The correct answer is, 'It is better for me to have high LDL levels and low HDL levels.' This statement indicates a need for further teaching because high LDL levels contribute to atherosclerosis, while high HDL levels can protect against heart disease. The client should understand the importance of lowering LDL levels and increasing HDL levels to maintain good heart health. Choice A is correct as desiring HDL levels over 50 is a positive goal. Choice B is correct as it reflects the ideal scenario of high HDL and low LDL levels. Choice D is correct as a total cholesterol below 200 is a common goal for heart health. Therefore, Choice C is incorrect as it suggests an opposite and unhealthy relationship between LDL and HDL levels.

Correct Answer: B

Rationale: When drawing a blood specimen from a central line, the healthcare professional should disconnect any infusions that are currently running and that could contaminate the specimen. It is important to use a minimum size of a 10 cc syringe when using a central line to avoid placing too much pressure on the catheter. Cleaning the cap with alcohol and attaching a 5 cc syringe is not appropriate as a larger syringe size should be used for this procedure. Drawing 5 cc of a blood sample to discard and flushing with saline after the sample are correct steps in the process of drawing a blood specimen from a central line.

Correct Answer: C

Rationale: Ulcerative colitis can lead to symptoms such as abdominal pain, fever, diarrhea, and weight loss. This condition may impact the absorption of certain nutrients, including magnesium. Therefore, patients with chronic gastrointestinal conditions like ulcerative colitis should be screened for electrolyte imbalances related to impaired digestion. Hyperthyroidism, arthritis, and depression do not typically directly affect magnesium levels in the same way as gastrointestinal conditions like ulcerative colitis.
