A nurse is assessing the fontanels of an 8-month-old infant. Which of the following findings should the nurse recognize as an expected finding
The anterior fontanel is open.
Both fontanels are the same size.
The posterior fontanel is open.
Both fontanels show moulding
The Correct Answer is A
Choice A reason
The anterior fontanel is open is the correct answer. An expected finding in an 8-month-old infant is that the anterior fontanel (the soft spot on the top of the baby's head) is open. The fontanelles are spaces between the bones of an infant's skull that allow for the baby's brain to grow and the skull to mould during birth.
The anterior fontanel typically remains open until the baby is around 18 to 24 months old, with the closure process starting sometime after 9 months of age. Therefore, at 8 months of age, it is normal for the anterior fontanel to still be open.
Choice B reason:
Both fontanels are the same size is incorrect. Both fontanels are usually not the same size. The anterior fontanel is larger and diamond-shaped, while the posterior fontanel is smaller and triangular.
Choice C reason:
The posterior fontanel is open is incorrect. The posterior fontanel, located at the back of the baby's head, usually closes earlier than the anterior fontanel. It typically closes within the first few months after birth, so it is not expected to be open at 8 months of age.
Choice D reason
Both fontanels show molding is incorrect. Molding refers to the temporary shaping of the baby's head during birth due to the pressure exerted during the passage through the birth canal. By 8 months of age, the molding typically resolves, and the baby's head should have a more rounded appearance.

Correct Answer is ["A","C"]
Explanation
A: Review the need for the indwelling urinary catheter daily.
This is correct because indwelling catheters should be removed as soon as possible to reduce the risk of urinary tract infection (UTI).
B: Place the drainage bag on the bed when transporting the client.
This is incorrect because the drainage bag should be kept below the level of the bladder and should not touch the floor to prevent the backflow of urine and contamination of the catheter.
C: Use soap and water to provide perineal care.
This is correct because soap and water can help to remove bacteria and debris from the meatus and prevent infection.
D: Encourage the client to drink 3000 mL of fluid daily.
This is incorrect because the client has a fluid restriction of 1000 mL daily due to heart failure. Excessive fluid intake can worsen the client’s condition and increase the workload of the heart.
E: Change the indwelling urinary catheter tubing every 3 days.
This is incorrect because changing the catheter tubing can increase the risk of infection by breaking the closed drainage system. The catheter tubing should only be changed when it is visibly soiled or malfunctioning.
F: Empty the drainage bag when it is half full.
This is incorrect because the drainage bag should be emptied at least every 8 hours or when it is one-third full to prevent back pressure and infection.
Correct Answer is D
Explanation
The correct answer is choiced. A client who is taking warfarin and has an INR of 1.8.
Choice A rationale:
An induration after a Mantoux test indicates a positive reaction, but it does not necessarily require immediate follow-up unless the induration is significant and the client has risk factors for tuberculosis.
Choice B rationale:
Sodium phosphate is commonly used as a bowel preparation for colonoscopy. This does not typically require follow-up unless the client experiences adverse effects such as dehydration or electrolyte imbalance.
Choice C rationale:
A potassium level of 3.6 mEq/L is within the normal range (3.5-5.0 mEq/L). Therefore, this finding does not require follow-up.
Choice D rationale:
An INR of 1.8 for a client taking warfarin is below the therapeutic range for most indications (typically 2.0-3.0). This requires follow-up to adjust the warfarin dosage to achieve the desired anticoagulation effect.
