Correct Answer: C

Rationale: The document dated 2003 supersedes the previous version and should be used as a basis for care directions. The nurse should follow the 2003 version, place it in the chart, and communicate the update appropriately to ensure that the most current care directions are followed. Choices A and B are incorrect because the 1998 version is now outdated, and the nurse should not rely on it for care decisions. Choice D is incorrect because the nurse should not delay following the updated document, and seeking clarification from the unit manager can lead to avoidable delays in care.

Correct Answer: D

Rationale: After ensuring the client's safety from the faulty electric bed, the nurse should prioritize preparing an incident report. This report documents the details of what happened and is crucial for quality improvement and risk management. Choice A, discussing the matter with the client's significant others, may be important in some cases but is not the immediate priority after a safety incident. Choice B, documenting the incident in the client's record, is necessary but should be preceded by preparing an incident report. Choice C, notifying the physician, is important but not as urgent as preparing the incident report to ensure timely reporting and investigation of the safety issue.

Correct Answer: A

Rationale: The correct answer is 'specific.' Specificity refers to the ability of a test to correctly identify individuals who do not have a particular disease. In this case, when the client's lab culture report is negative for the suspected infection, a specific test would correctly identify that the client does not have the disease. 'Sensitive' (Choice B) is incorrect as sensitivity refers to the ability of a test to correctly identify individuals who do have the disease. 'Negative culture' (Choice C) is incorrect as it does not describe the test's ability but rather the result itself. 'Marginal finding' (Choice D) is irrelevant to the concept being tested in this question.

Correct Answer: D

Rationale: The correct answer is infant rice cereal. Single-grain infant cereals are recommended as the first solid food because they are easily digestible and have added iron content. Choice C, yogurt, is incorrect because yogurt is a milk product and should be delayed until the child is 12 months old due to the risk of milk allergy. Choices A and B are incorrect because fruits and vegetables are typically introduced after cereals to help the infant get accustomed to solid foods gradually.

Correct Answer: B

Rationale: The correct answer is that the new graduate irrigates the pressure ulcer with half-strength hydrogen peroxide. Pressure ulcers should not be cleaned with substances that are cytotoxic, such as hydrogen peroxide or betadine. This can cause further damage to the wound and delay the healing process. Choice A is incorrect because irrigating the pressure ulcer with normal saline is an appropriate practice. Choice C is incorrect because packing the wound with sterile kerlix soaked in normal saline is also an appropriate step. Choice D is incorrect because applying a Duoderm dressing after cleansing is a standard procedure in wound care.
