A nurse is collecting data from a client who has an NG tube set to low intermittent suction. Which of the following findings indicates hypomagnesemia?
Bone pain
Drowsiness
Bowel hypomotility
Positive Chvostek's sign
The Correct Answer is D
A. Bone pain: Bone pain is not a characteristic finding of hypomagnesemia. Hypomagnesemia is an electrolyte imbalance, and bone pain is not a typical symptom associated with it.
B. Drowsiness: Drowsiness may occur in hypomagnesemia, but it is not a specific or characteristic sign of this condition. Other electrolyte imbalances and medical conditions can also cause drowsiness.
C. Bowel hypomotility: Hypomagnesemia can cause bowel hypomotility (decreased bowel movements), but it is not the most specific finding associated with this condition.
D. Positive Chvostek's sign: Correct. Hypomagnesemia can lead to neuromuscular irritability, and a positive Chvostek's sign is a clinical manifestation of this condition. A positive Chvostek's sign is elicited by tapping the facial nerve (at the level of the zygomatic arch) and observing a
twitching of the facial muscles, which indicates increased neuromuscular excitability.

Correct Answer is A
Explanation
A. Administer an analgesic 30 min before starting the procedure: Correct. Before performing wound irrigation, it is essential to provide pain relief to the client. Administering an analgesic 30 minutes before the procedure will help manage pain during wound irrigation.
B. Hold the syringe 5 cm (2 in) above the upper end of the wound: This action does not contribute to proper wound irrigation. The nurse should direct the irrigation solution to the wound site to cleanse it effectively.
C. Place the irrigation solution in a basin of cool water: Using cool water is not the best practice for wound irrigation. The irrigation solution should be at room temperature or a temperature specified by the healthcare provider.
D. Perform the wound irrigation with a 10mL syringe with an angiocatheter: Wound irrigation typically requires a larger volume of fluid to adequately cleanse the wound. A 10mL syringe may not be sufficient, and using an angiocatheter is not appropriate for wound irrigation. A larger syringe or irrigation solution bag with an appropriate wound irrigation tool is usually used.
Correct Answer is D
Explanation
A: A nasal cannula provides a low to moderate concentration of oxygen and is not suitable for a client experiencing severe difficulty breathing.
B: A simple face mask provides a higher concentration of oxygen than a nasal cannula but may not deliver a high enough concentration for a client experiencing severe respiratory distress.
C: A Venturi mask can provide a precise and adjustable concentration of oxygen but may not deliver the highest concentration needed in this scenario.
D: A nonrebreather mask can deliver the highest concentration of oxygen (up to 100%) and is the most appropriate choice for a client experiencing severe difficulty breathing.
