A nurse is caring for a child who has cystic fibrosis and requires postural drainage.
Which of the following actions should the nurse take?
Hold hand flat to perform percussions on the child.
Perform the procedure twice each d
Perform the procedure prior to meals.
Administer a bronchodilator after the procedure
The Correct Answer is C
The correct answer is choice C. Perform the procedure prior to meals.
This is because postural drainage involves positioning the child in different ways to help drain the mucus from the lungs.
If the child has a full stomach, this can cause nausea, vomiting, or aspiration. Therefore, the nurse should perform the procedure before meals or at least 1 hour after meals.
Choice A is wrong because the nurse should not hold the hand flat to perform percussions on the child.
Percussions are rhythmic clapping on the chest wall to loosen the mucus. The nurse should use a cupped hand to create a small air pocket that enhances the vibrations and prevents bruising.
Choice B is wrong because the nurse should not perform the procedure twice a day. The recommended frequency of postural drainage is 3 to 4 times a day, or more if needed, depending on the child’s condition and tolerance.
Choice D is wrong because the nurse should not administer a bronchodilator after the procedure.
A bronchodilator is a medication that relaxes and widens the airways, making it easier to breathe. The nurse should administer a bronchodilator before the procedure to enhance the effectiveness of postural drainage.

Correct Answer is A
Explanation
The correct answer is choice A. INR.
Warfarin is a vitamin K antagonist that inhibits the synthesis of factors II, VII, IX, and X in the liver.
These factors are part of the extrinsic and common pathways of coagulation, which are measured by the prothrombin time (PT) and the international normalized ratio (INR).
The INR is a standardized way of reporting the PT that accounts for the variability of different reagents and instruments.
The INR is used to monitor the therapeutic effect of warfarin and to adjust the dose accordingly.
The target INR range depends on the indication for warfarin, but it is usually between 2 and 3 for most conditions.
Choice B is wrong because fibrinogen level is not affected by warfarin.
Fibrinogen is a precursor of fibrin, which forms the final step of the coagulation cascade.
Fibrinogen level can be decreased in conditions such as disseminated intravascular coagulation (DIC), liver disease, or severe bleeding. Choice C is wrong because aPTT is not affected by warfarin.
aPTT measures the intrinsic and common pathways of coagulation, which are mainly dependent on factors VIII, IX, XI, and XII.
These factors are not inhibited by warfarin.
aPTT is used to monitor the effect of heparin, a direct antithrombin agent that inhibits thrombin and factor Xa.
Choice D is wrong because platelet count is not affected by warfarin.
Platelets are cell fragments that adhere to damaged blood vessels and form aggregates to initiate hemostasis.
Platelet count can be decreased in conditions such as immune thrombocytopenia (ITP), heparin-induced thrombocytopenia (HIT), or bone marrow suppression.
Normal ranges:
- INR: 0.8-1.2
- Fibrinogen: 200-400 mg/dL
- aPTT: 25-35 seconds
- Platelet count: 150-450 x 10^9/L References:
Correct Answer is D
Explanation
The correct answer is choice D. Shuffling gait. This is because shuffling gait is a common manifestation of pseudoparkinsonism, which is a condition that mimics the symptoms of Parkinson’s disease due to the use of certain medications that block dopamine receptors, such as haloperidol. Pseudoparkinsonism can cause slowed movements, muscle stiffness, tremor, and postural instability.
Choice A. Nonreactive pupils is wrong because this is not a typical feature of pseudoparkinsonism or Parkinson’s disease.
Nonreactive pupils can be caused by other conditions, such as brain injury, drugs, or eye diseases.
Choice B. Serpentine limb movement is wrong because this is a characteristic of tardive dyskinesia, another drug-induced movement disorder that can result from long-term use of dopamine receptor blocking agents. Tardive dyskinesia causes involuntary movements of the face, tongue, and limbs that are often writhing or twisting.
Choice C. Smacking lips is wrong because this is also a sign of tardive dyskinesia, not pseudoparkinsonism. Smacking lips is one of the orofacial movements that can occur in tardive dyskinesia due to abnormal muscle contractions.
