The nurse is planning to administer a tuberculin test with a 27-gauge, 5/8-inch needle. At which angle will the nurse insert the needle?
15 degree
90 degree
30 degree
45 degree
The Correct Answer is A
A. The tuberculin test is administered intradermally, and the needle should be inserted at a 15-degree angle to ensure the medication is delivered just under the surface of the skin.
B. A 90-degree angle is used for intramuscular injections, not for intradermal tests like the tuberculin test.
C. A 30-degree angle is commonly used for subcutaneous injections and is too deep for an intradermal injection.
D. A 45-degree angle is also used for subcutaneous injections but is not suitable for intradermal injections.

Correct Answer is D
Explanation
A. Grief evaluation refers to assessing the grief process rather than actively engaging in supportive dialogue, which is not the primary focus of the nurse's action.
B. Pain-management techniques would not apply directly to this context, as the discussion centers on emotional support rather than physical pain.
C. Palliative care encompasses a broader approach to managing patients with serious illnesses but does not specifically address the emotional support provided in this situation.
D. The nurse's action of discussing the child's life and death helps the parents express their grief and memories, thereby facilitating normal mourning, making this the most appropriate principle demonstrated.
Correct Answer is D
Explanation
A. Chest physiotherapy is used to mobilize secretions and improve lung function, not specifically for increasing stroke volume or preload.
B. Diuretics would decrease preload by removing excess fluid, which is counterproductive in a patient with inadequate stroke volume related to decreased preload.
C. Vasodilators can further decrease preload and are not appropriate in this scenario where preload needs to be increased.
D. Intravenous (IV) fluids are administered to increase preload and improve stroke volume by enhancing the circulating blood volume.
