When teaching a client about insulin administration, the nurse should include which instruction?

Correct Answer: D

Rationale: When mixing two types of insulin in one syringe, it is essential to draw up the clear insulin first before drawing up the cloudy insulin. This sequence prevents the clear insulin from becoming contaminated with the cloudy insulin and ensures accurate dosing. Drawing up the clear insulin first helps to minimize the risk of inaccurate dosing and maintains the effectiveness of the insulin being administered.

Correct Answer: C

Rationale: This is an appropriate question to ask the parents because determining the time the infant was found is important for investigating the circumstances surrounding the sudden infant death syndrome (SIDS) event. Understanding the timeline can help healthcare providers gather valuable information to determine the cause of death and evaluate any potential contributing factors. This question also allows the healthcare team to better understand the sequence of events leading up to the tragic outcome and offer support to the grieving parents. Asking about the time the infant was found is non-accusatory and focuses on gathering relevant details for the medical evaluation.

Correct Answer: C

Rationale: The correct action to prevent rheumatic fever is to refer children with sore throats for throat cultures (Choice C). Rheumatic fever is caused by an abnormal immune response to a bacterial infection with group A Streptococcus. By promptly diagnosing and treating streptococcal infections with antibiotics, the risk of developing rheumatic fever can be minimized. Conducting throat cultures for children with sore throats helps identify streptococcal infections and allows for appropriate antibiotic treatment, thereby preventing the progression to rheumatic fever. Encouraging routine hypertensive screenings (Choice A) and conducting routine occult blood screenings (Choice B) are not directly related to the prevention of rheumatic fever. Recommending salicylates instead for minor discomforts (Choice D) is contraindicated in cases of suspected or confirmed streptococcal infections due to the risk of worsening symptoms and potentially triggering rheumatic fever.

Correct Answer: C

Rationale: Romberg's test is a neurological test that assesses the function of the dorsal columns of the spinal cord, which are responsible for proprioception and vibration sensations. A lumbar injury can affect these dorsal columns, leading to impaired proprioception. Therefore, the Romberg's test would be affected due to the compromised sensory input from the lower extremities. This test usually involves asking the patient to stand with feet together and eyes closed to assess balance and proprioception.

Correct Answer: D

Rationale: Heavy meals before bedtime can disrupt sleep.
