A nurse is reviewing the medical records of four clients who have an acid-base imbalance. The nurse should recognize that which of the following clients is at risk for respiratory alkalosis?
A client who is taking a thiazide diuretic.
A client who is vomiting.
A client who has salicylate intoxication.
A client who has hypoventilation.
The Correct Answer is C
The correct answer is Choice C.
Choice A rationale: Thiazide diuretics cause potassium and chloride loss, leading to metabolic alkalosis, not respiratory alkalosis. Hypokalemia decreases hydrogen ion excretion, increasing bicarbonate levels. Metabolic alkalosis is characterized by pH >7.45 and HCO₃⁻ >26 mEq/L rather than decreased PaCO₂.
Choice B rationale: Vomiting leads to metabolic alkalosis due to gastric acid loss. Hydrogen ion depletion increases bicarbonate concentration, shifting pH above normal. Arterial blood gases typically show increased HCO₃⁻ (>26 mEq/L) with a compensatory increase in PaCO₂ (>45 mmHg), not respiratory alkalosis.
Choice C rationale: Salicylate intoxication initially induces hyperventilation, reducing PaCO₂ levels below 35 mmHg and increasing pH above 7.45, leading to respiratory alkalosis. As toxicity progresses, metabolic acidosis may develop due to lactic acid accumulation, but early stages primarily present with respiratory alkalosis.
Choice D rationale: Hypoventilation leads to CO₂ retention, increasing PaCO₂ above 45 mmHg, forming carbonic acid (H₂CO₃) and causing respiratory acidosis. Blood gases show pH <7.35 with elevated PaCO₂, not respiratory alkalosis, which is caused by excessive CO₂ elimination through hyperventilation.

Correct Answer is D
Explanation
Choice A rationale:
Telangiectatic nevi are commonly known as "stork bites”. or "angel kisses”. and are superficial vascular areas commonly found on the nape of the neck or the eyelids of newborns? These are benign and pose no significant health risks.
Choice B rationale:
Erythema toxicum is a common, benign skin rash that appears in the first few days of life. It presents as small, raised red spots with a surrounding halo and is not related to a nuchal cord.
Choice C rationale:
Periauricular papillomas, also known as "ear tags,”. are small, skin-coloured nodules that can be found near the external ear. They are also benign and unrelated to a nuchal cord.
Choice D rationale:
Facial petechiae are tiny, red or purple pinpoint spots on the skin caused by minor haemorrhages. In newborns, facial petechiae can be associated with a nuchal cord, which is a condition where the umbilical cord is wrapped around the baby's neck during delivery. This condition is relatively common and usually resolves without complications. The nurse should monitor the baby for any signs of distress or complications related to the nuchal cord.
Correct Answer is ["B","C"]
Explanation
Choice A rationale:
Newborn weight of 2.948 kg (6 lb 8 oz) does not place the client at risk for postpartum hemorrhage. Newborn weight is not directly related to the risk of postpartum hemorrhage in the mother.
Choice B rationale:
History of uterine atony places the client at risk for postpartum hemorrhage. Uterine atony is the most common cause of postpartum hemorrhage and refers to the inability of the uterus to contract effectively after childbirth, leading to excessive bleeding.
Choice C rationale:
Labor induction with oxytocin places the client at risk for postpartum hemorrhage. Oxytocin is commonly used to induce labor or augment contractions, but it can cause uterine hyperstimulation, leading to increased risk of postpartum hemorrhage.
Choice D rationale:
History of human papillomavirus (HPV) does not place the client at risk for postpartum hemorrhage. HPV is a sexually transmitted infection and does not have a direct connection to the risk of postpartum hemorrhage.
Choice E rationale:
Vacuum-assisted delivery places the client at risk for postpartum hemorrhage. Vacuum assisted delivery involves using a vacuum device to assist in the baby's delivery, and it can cause trauma to the birth canal, leading to increased bleeding risk in the mother.
