1. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which laboratory value requires immediate intervention?

A. Arterial blood gas (ABG) values
B. Serum potassium level
C. Serum sodium level
D. Blood glucose level

Correct answer: A

Rationale: The correct answer is A: Arterial blood gas (ABG) values. In a client with COPD and pneumonia, ABG values are crucial as they provide essential information about the client's respiratory status, including oxygenation and acid-base balance. Immediate intervention may be required to optimize respiratory function based on ABG results. Serum potassium, sodium, and blood glucose levels are important parameters to monitor in various conditions but are not as directly related to the respiratory status in a client with COPD and pneumonia. Therefore, they do not require immediate intervention compared to ABG values.

2. A client with chronic kidney disease (CKD) is scheduled for a hemodialysis session. Which laboratory value should the nurse monitor closely?

A. Serum potassium
B. Serum creatinine
C. Serum sodium
D. Serum chloride

Correct answer: C

Rationale: The correct answer is C: Serum sodium. In a client with chronic kidney disease (CKD) scheduled for hemodialysis, monitoring serum sodium levels closely is essential. Hemodialysis can cause rapid shifts in sodium levels, leading to electrolyte imbalances. While serum potassium (choice A) is important to monitor in CKD, it is not the most crucial before hemodialysis. Serum creatinine (choice B) is an indicator of kidney function but is not the most immediate concern before hemodialysis. Serum chloride (choice D) is not typically the primary electrolyte of concern in CKD patients before hemodialysis.

3. An adult client comes to the clinic and reports his concern over a lump that 'just popped up on my neck about a week ago.' In performing an examination of the lump, the nurse palpates a large, non-tender, hardened left subclavian lymph node. There is no overlying tissue inflammation. What do these findings suggest?

A. Malignancy
B. Infection
C. Benign cyst
D. Lymphadenitis

Correct answer: A

Rationale: The findings of a large, non-tender, hardened lymph node, especially in the absence of overlying tissue inflammation, are indicative of malignancy. These characteristics raise suspicion for cancer, prompting the need for further investigation. Choice B, Infection, is incorrect because infection would typically present as a tender and possibly swollen lymph node. Choice C, Benign cyst, is incorrect as cysts are usually soft and movable. Choice D, Lymphadenitis, is incorrect as lymphadenitis usually presents with tender and enlarged lymph nodes in response to an infection.

4. The mother of a one-month-old boy born at home brings the infant to his first well-baby visit. The infant was born two weeks after his due date and is described as a 'good, quiet baby' who almost never cries. To assess for hypothyroidism, what question is most important for the nurse to ask the mother?

A. Has your son had any immunizations yet?
B. Is your son sleepy and difficult to feed?
C. Are you breastfeeding or bottle-feeding your son?
D. Were any relatives born with birth defects?

Correct answer: B

Rationale: The correct answer is B. Excessive sleepiness and difficulty feeding can be signs of hypothyroidism in infants. Asking about the infant's sleepiness and feeding pattern is crucial in assessing for hypothyroidism. Choice A is incorrect because immunizations are not directly related to hypothyroidism. Choice C is about feeding method and not specific to hypothyroidism. Choice D is unrelated as it asks about relatives with birth defects, which does not directly assess the infant's condition.

5. A client with liver cirrhosis is admitted with ascites and jaundice. Which assessment finding is most concerning?

A. Serum albumin of 3.0 g/dL
B. Bilirubin of 3.0 mg/dL
C. Ammonia level of 80 mcg/dL
D. Prothrombin time of 18 seconds

Correct answer: C

Rationale: An ammonia level of 80 mcg/dL is elevated and concerning in a client with liver cirrhosis, as it may indicate hepatic encephalopathy. Elevated ammonia levels can lead to cognitive impairment, altered mental status, and even coma. Serum albumin, bilirubin, and prothrombin time are also important markers in liver cirrhosis but are not as directly associated with the risk of hepatic encephalopathy as elevated ammonia levels.
