A nurse is reviewing laboratory results for a client who has metabolic alkalosis. Which of the following blood gas values should the nurse expect?
pH 7.36 (7.35 to 7.45), PaCO2 38 mm Hg (35 to 45 mmHg) HCO3 25 mEq/L (22 to 26 mEq/L)
pH 7.48 (7.35 to 7.45), PaCO, 32 mm Hg (35 to 45 mm Hg). HCO3 24 mEq/L (22 to 26 mE q/L)
pH 7.46 (7.35 to 7.45). PaCO2 36 mm Hg (35 to 45 mm Hg). HCO3 29 mEq/L (22 to 26 mEq/L)
pH 7.26 (7.35 to 7.45). PaCO, 35 mm Hg (35 to 45 mm Hg). HCO3 18 mEq/L (22 to 26 mEq/L)
The Correct Answer is C
A) pH 7.36 (7.35 to 7.45), PaCO2 38 mm Hg (35 to 45 mmHg), HCO3 25 mEq/L (22 to 26 mEq/L): This is a normal set of arterial blood gas (ABG) values, with a pH within normal range, a normal PaCO2, and a normal HCO3. It does not suggest metabolic alkalosis.
B) pH 7.48 (7.35 to 7.45), PaCO2 32 mm Hg (35 to 45 mm Hg), HCO3 24 mEq/L (22 to 26 mEq/L): Although the pH is elevated, indicating alkalosis, the PaCO2 is slightly low, and the bicarbonate (HCO3) is within the normal range. This set of values does not indicate metabolic alkalosis, but could indicate respiratory alkalosis or compensated alkalosis.
C) pH 7.46 (7.35 to 7.45), PaCO2 36 mm Hg (35 to 45 mm Hg), HCO3 29 mEq/L (22 to 26 mEq/L): This is consistent with metabolic alkalosis. The elevated pH (alkalosis) combined with an increased bicarbonate level (HCO3 > 26 mEq/L) and a normal PaCO2 suggests metabolic alkalosis, as the kidneys retain bicarbonate to compensate for the condition.
D) pH 7.26 (7.35 to 7.45), PaCO2 35 mm Hg (35 to 45 mm Hg), HCO3 18 mEq/L (22 to 26 mEq/L): This set of values indicates acidosis, not alkalosis. The pH is low, indicating acidosis, and the bicarbonate (HCO3) is also low, which suggests metabolic acidosis. The PaCO2 is normal, which further supports a metabolic origin of the acidosis.

Correct Answer is B
Explanation
A) *The client's partner visited earlier today for 2 hours: While this information is helpful for the personal context of the client, it is not essential to the clinical care of the client or a critical part of the handoff. The change-of-shift report should focus on relevant clinical information that affects ongoing care, such as treatment responses, medications, or changes in condition.
B) "The client reports pain is reduced when he is positioned on his side": This is important clinical information that should be included in the report. It provides insight into the client’s current comfort measures and pain management strategies. Sharing how the client’s pain can be alleviated will help the next nurse provide the most effective care and manage the client's comfort.
C) "The client received the prescribed antibiotic every 8 hours": While medication administration is an essential part of the report, this specific detail is unnecessary if the medication administration schedule is already part of the client's medical record or the nurse's medication administration documentation. The change-of-shift report should focus on whether the client has had any reactions, responses, or issues related to the medication, rather than simply repeating the schedule.
D) "The client's mother died 4 years ago from breast cancer": This personal history may be relevant to understanding the client's emotional well-being but is not essential in a clinical report unless it directly impacts current care. If the client's grief or family history affects their current health status (such as in the case of emotional distress, family health risks, or health behaviors), it may be relevant, but it's generally not a priority in a shift report unless it has immediate implications for care.
Correct Answer is A
Explanation
A) Drain the tub water before the client gets out: Draining the water before the client gets out of the tub is the safest option. This helps prevent the risk of slipping or falling, as the water level will lower once the client begins to stand. Additionally, it ensures that the client can safely exit the tub without the danger of being unbalanced or disoriented by the water.
B) Check on the client every 10 min during the bath: While monitoring the client during the bath is important, checking every 10 minutes may not be frequent enough to ensure their safety, especially for clients who have mobility or cognitive issues. Ideally, the nurse should stay with or observe the client more closely or provide assistance if needed. Continuous supervision is preferred, particularly if the client is at risk for falls or other complications.
C) Add bath oil to the water after the client gets into the tub: Bath oils can create a slippery surface, which could increase the risk of falls or accidents. It's generally better to avoid adding oils to the bath water, as they can make the tub and the client’s skin slick, posing safety hazards. If oil is necessary for skin care, it should be applied to the skin after the bath, not in the water.
D) Allow the client to remain in the bath for 30 min: While the client may enjoy a bath, staying in the tub for too long can lead to skin irritation, dehydration, or overheating, especially for older adults or clients with medical conditions. The client should not stay in the water for prolonged periods. A typical recommendation would be to allow the bath to last about 10-20 minutes, depending on the client’s condition and safety.
