A 13-year-old client with type 1 diabetes is admitted to the hospital with a blood glucose level of 450 mg/dL. The client is lethargic and has fruity-smelling breath. What is the nurse's priority action?

Correct Answer: B

Rationale: The correct priority action for the nurse is to start an IV infusion of normal saline. The client's presentation with lethargy, fruity-smelling breath, and high blood glucose level indicates diabetic ketoacidosis (DKA). IV fluids are essential to correct dehydration and help stabilize the client's condition. Checking for ketones in the urine is important, but fluid replacement takes precedence to address the immediate risk of dehydration and electrolyte imbalances. Administering insulin is also a crucial intervention for DKA, but fluid resuscitation should first be initiated.

Correct Answer: C

Rationale: A serum potassium level of 3.0 mEq/L is significantly low and indicates hypokalemia, which can lead to serious complications such as cardiac arrhythmias. Therefore, it is crucial for the nurse to report this finding promptly to the healthcare provider for immediate intervention. The other findings are not as critical in this situation. Gastric output of 100 mL in the last 8 hours may be expected in a patient with persistent vomiting. The shift intake of IV fluids and ice chips indicates fluid replacement, which is important but not as urgent as correcting electrolyte imbalances. A serum pH of 7.45 is within the normal range and does not indicate an immediate concern.

Correct Answer: A

Rationale: In this scenario, the best course of action for the nurse is to review the child's asthma action plan. By doing so, the nurse can assess the current asthma management, ensure that the child is using the rescue inhaler correctly, and make any necessary adjustments to the treatment plan. Reviewing the asthma action plan helps in identifying triggers, proper use of medications, and when to seek medical help. Administering a dose of the rescue inhaler without assessing the current management plan may not address the underlying issue. Instructing the parents to increase the dose of the controller medication without proper evaluation can lead to inappropriate medication adjustments. Scheduling a follow-up appointment in one week is not the immediate action needed to address the child's current symptoms.

Correct Answer: B

Rationale: In cystic fibrosis, thick mucus obstructs the airways, making it difficult to clear from the lungs. Cough suppressants can help reduce the discomfort associated with persistent coughing, allowing the child to cough more effectively to clear the mucus, thus promoting pulmonary function. Chest physiotherapy, not exercise, helps mobilize the mucus. Oxygen therapy may be needed but is not the most important for promoting pulmonary function in this case.

Correct Answer: A

Rationale: When dealing with seborrheic dermatitis (cradle cap) in infants, it is essential to use a soft brush and gently scrub the affected area to help remove the scales. This process can aid in managing the condition and preventing further build-up. It is important to be gentle to avoid irritating the baby's delicate skin. Choice B is incorrect as gentle scrubbing with a soft brush can help in the removal of scales. Choice C is incorrect because regular but gentle washing is recommended to manage cradle cap. Choice D is incorrect as using specialized shampoos designed for cradle cap is usually recommended over soap and water.

Correct Answer: B

Rationale: The correct answer is explaining the association between drinking soda and dental caries. Soda consumption can lead to tooth decay and cavities, so it is crucial to educate the mother about this to prevent dental issues in the child.

Correct Answer: D

Rationale: The correct answer is D. Wearing long sleeves and pants is an effective measure to prevent tick bites, which can transmit Lyme disease. Ticks are commonly found in wooded areas and tall grass, so covering exposed skin helps reduce the risk of tick bites and subsequently lowers the risk of contracting Lyme disease. Choices A, B, and C do not directly address the mode of transmission of Lyme disease. Option A pertains to respiratory protection against dust, Option B focuses on wound care, and Option C relates to water safety, none of which are directly related to preventing Lyme disease transmission.

Correct Answer: B

Rationale: The correct answer is to notify the healthcare provider immediately. The child's presentation of sudden, severe abdominal pain in the lower right abdomen is highly concerning for appendicitis, a medical emergency. Promptly notifying the healthcare provider is crucial for further evaluation and management. Administering pain medication as the first action might mask symptoms and delay diagnosis. Starting an IV line for fluid administration and obtaining a complete blood count are important interventions but should come after healthcare provider notification.

Correct Answer: D

Rationale: The priority intervention for a client who has taken an acetaminophen overdose is to administer N-acetylcysteine promptly. N-acetylcysteine is the antidote for acetaminophen overdose and helps prevent liver damage. Activated charcoal may be used in certain cases, but N-acetylcysteine takes precedence as it directly counteracts the toxic effects of acetaminophen. Continuous cardiac monitoring and gastric lavage are not the priority interventions for acetaminophen overdose. Administering N-acetylcysteine is crucial to prevent liver damage and address the overdose, making it the most urgent action in this scenario.
