HESI Fundamentals Test Bank

Correct Answer: B

Rationale: The correct answer is B: Liver function tests. While a client is taking metformin, monitoring liver function tests is crucial to assess for potential hepatic side effects. Metformin is primarily eliminated by the liver, and monitoring liver function tests helps in early detection of any liver-related complications. Choices A, C, and D are incorrect. A complete blood count (CBC) is not specifically required for monitoring metformin therapy. Serum electrolytes are not directly impacted by metformin, making it less relevant for monitoring this medication. Renal function tests are important for some other diabetes medications, but in the case of metformin, liver function tests take precedence due to its hepatic metabolism.

Correct Answer: B

Rationale: The correct sequence for obtaining a clean catch urine specimen involves first cleaning the meatus to prevent contamination, then initiating voiding to catch the midstream urine. This method ensures that the sample is as uncontaminated as possible, making choice B the correct sequence. Option A is incorrect as cleaning the meatus should be done before voiding. Option C is incorrect as it does not involve catching a midstream urine sample. Option D is incorrect as it suggests catching urine throughout the entire voiding process, which may lead to contamination.

Correct Answer: B

Rationale: The correct action for the nurse to include when assessing the client's gag reflex is to place a tongue blade on the back half of the tongue. This method effectively tests the gag reflex without causing discomfort. Choice A is incorrect because offering small sips of water through a straw does not assess the gag reflex. Choice C is incorrect as using a penlight to observe the back of the oral cavity does not directly assess the gag reflex. Choice D is incorrect since auscultating breath sounds after the client swallows does not evaluate the gag reflex.

Correct Answer: C

Rationale: The correct answer is 'C: Sore throat.' Oxygen toxicity can manifest with symptoms like a sore throat, cough, chest pain, difficulty breathing, and fatigue. However, a sore throat can be an early indicator of oxygen toxicity and should prompt immediate attention. Nasal congestion, cough, and fatigue are not specific indicators of oxygen toxicity but could be related to other factors in a client with COPD receiving oxygen therapy.

Correct Answer: A

Rationale: A blood glucose of 100 mg/dL is relatively low for administering insulin, especially if the client has not eaten adequately; further assessment and contacting the provider are necessary. Hypoglycemia can be a serious concern when administering insulin, and a blood glucose level of 100 mg/dL indicates a risk of hypoglycemia. Holding the insulin and contacting the healthcare provider is crucial to prevent hypoglycemia-related complications. Choices B, C, and D are not immediate concerns for holding insulin as they do not directly indicate a risk of hypoglycemic events.
