Correct Answer: B

Rationale: The correct first step before administering a blood transfusion is to verify that the client's blood type matches the blood product. This step is crucial to prevent transfusion reactions due to incompatibility. Choice A is incorrect because blood should not be administered through an IV push for a blood transfusion. Choice C is incorrect because it is not necessary for the client to eat before a blood transfusion. Choice D is incorrect because administering a diuretic is not a standard practice before starting a blood transfusion.

Correct Answer: A

Rationale: The correct answer is A: Decerebrate posturing. Decerebrate posturing is an abnormal body posture characterized by rigid extension of the arms and legs, which indicates severe brainstem injury affecting the midbrain and pons. This posture suggests dysfunction or damage to neural pathways controlling muscle tone. Choice B, hypervigilance, is not typically associated with brainstem injury but rather with increased alertness and arousal. Choice C, absence of deep tendon reflexes, is not a specific finding related to brainstem injury. Choice D, a Glasgow Coma Scale score of 15, indicates a fully awake and alert state, which is not expected in a client with a brainstem injury.

Correct Answer: D

Rationale: The correct answer is D, Ginger ale. A clear liquid diet includes fluids that are see-through and easily digestible. Ginger ale is a carbonated beverage that is allowed on a clear liquid diet. Orange sherbet, choice B, is not suitable for a clear liquid diet as it contains dairy products and solid particles, which are not transparent. Lemon-lime sports drinks, choice A, may contain added colorings or particles that are not allowed on a clear liquid diet. Black coffee, choice C, is also not recommended on a clear liquid diet as it is not a clear liquid and contains substances that may be hard to digest.

Correct Answer: B

Rationale: In this scenario, with the client's cervix dilated to only 1 cm and an unengaged presenting part, the priority action is to apply the external fetal monitor. This allows for continuous monitoring of the fetal heart rate during early labor, which is crucial for assessing fetal well-being. Encouraging the client to bear down is not appropriate at 1 cm dilation, as it may not be effective and can lead to exhaustion. Providing the client with fluids or administering IV fluids may be necessary for hydration, but the immediate concern is monitoring fetal well-being.

Correct Answer: D

Rationale: The correct answer is D because a client with pneumonia and a new onset of confusion needs immediate evaluation for changes in neurological status. This could indicate a decline in respiratory status or potential complications such as hypoxia or sepsis. Option A, a client who is NPO and has dry mucous membranes, may need intervention but does not indicate an acute change in condition. Option B, a client with rotavirus who has been vomiting, requires assessment and intervention but does not pose an immediate threat to life. Option C, a client with a urinary catheter and cloudy urine, may indicate a urinary tract infection but does not require immediate attention compared to the client with new onset confusion and pneumonia.
