Question 1 of 5
The nurse notes small, pimple-like pustules all over the newborn's body. When charting the integumentary assessment of this newborn, which normal finding does the nurse note?
Correct Answer: C
Rationale: Small, pimple-like pustules on a newborn's body suggest erythema toxicum (C), a benign, self-limiting rash common in the first week of life, often with erythematous macules and pustules. Strawberry hemangiomas (A) are vascular growths, not pustular. Port-wine stains (B) are flat, purple birthmarks. Telangiectatic nevi simplex (D) are salmon-colored patches, not pustules. C is correct. Rationale: Erythema toxicum affects up to 70% of newborns, caused by an immune response, resolving without treatment, distinct from vascular or permanent lesions, aligning with normal neonatal skin findings.
Question 2 of 5
A client attached to mechanical ventilation suddenly becomes restless and pulls out the tracheostomy tube. Which is the nurse's priority intervention?
Correct Answer: D
Rationale: If a tracheostomy tube is dislodged, checking for spontaneous breathing (D) is the priority to assess airway patency and oxygenation need. Preparing for reintubation (A) or calling teams (B, C) follows. D is correct. Rationale: Assessing breathing determines if immediate reinsertion or oxygenation is urgent, guiding next steps per respiratory emergency standards, ensuring patient stability first.
Question 3 of 5
The nurse is reviewing the arterial blood gas results of an assigned client. Which arterial blood gases indicate metabolic alkalosis?
Correct Answer: D
Rationale: Metabolic alkalosis features high pH (>7.45) and elevated HCO3- (>26 mEq/L) with normal Pco2 (35-45 mm Hg). Option D (pH 7.48, Pco2 40, HCO3- 36) fits this, indicating excess base. A is respiratory acidosis. B is normal. C is compensated. D is correct. Rationale: High HCO3- from vomiting or diuretics causes alkalosis, uncompensated here, per ABG interpretation principles.
Question 4 of 5
A client is scheduled for a computed tomography (CT) of the brain with contrast. When reviewing the client's medical record, what significant finding should the nurse report to the primary healthcare provider before the diagnostic procedure?
Correct Answer: A
Rationale: Metformin (A) is significant before a CT with contrast due to lactic acidosis risk if renal function declines from contrast dye. NPO status (B) isn't critical for brain CT. Gadolinium (C) is MRI-related, not CT. Bowel prep (D) is irrelevant. A is correct. Rationale: Contrast can impair kidneys, exacerbating metformin toxicity, requiring provider adjustment, per radiology safety protocols.
Question 5 of 5
After a head injury, a client develops a deficiency of antidiuretic hormone (ADH). What should the nurse consider before assessing the patient about the response to secretion of ADH?
Correct Answer: B
Rationale: ADH deficiency (diabetes insipidus) post-head injury causes dilute urine (B) due to reduced water reabsorption. Osmolality increases (A) is a result, not a cause. GFR (C) isn't primarily affected. Reabsorption (D) decreases. B is correct. Rationale: Low ADH leads to polyuria with low urine concentration, a key assessment in DI, per endocrine trauma care.
