A nurse is preparing to administer an IM injection to a client who is obese. Which of the following actions should the nurse plan to take?

Select a 1-inch needle

Use a 45° angle when inserting the needle

Use the ventrogluteal site

Pinch the skin up during injection

Answer and Explanation

The Correct Answer is C

A. Incorrect. A 1-inch needle may not be long enough to reach the muscle layer in an obese client, which may result in subcutaneous injection and reduced absorption of the medication.
B. Incorrect. A 45° angle may not be appropriate for an IM injection, as it may cause the needle to enter at an oblique angle and miss the muscle layer or hit a bone or nerve.
C. Correct. The ventrogluteal site is preferred for IM injections in obese clients, as it has less subcutaneous fat and a large muscle mass that can accommodate larger volumes of medication.
D. Incorrect. Pinching the skin up during injection may cause the needle to enter at a shallow angle and deposit the medication in the subcutaneous tissue instead of the muscle layer.

Correct Answer is C

Explanation

- A. Hypotension is not an adverse effect of epinephrine, but rather a sign of anaphylaxis that epinephrine can help to reverse by causing vasoconstriction and increasing blood pressure.

- B. Report of tinnitus is not an adverse effect of epinephrine, but rather a symptom of aspirin toxicity, which can occur in some clients who take aspirin for allergic reactions.

- C. Report of chest pain is an adverse effect of epinephrine, as it can cause cardiac dysrhythmias, angina, and myocardial ischemia by increasing the heart rate and oxygen demand of the myocardium.

-D. Ecchymosis is not an adverse effect of epinephrine, but rather a sign of bleeding disorders or trauma that can cause bruising under the skin.

A. Measure the amount of time the child can hear the sound. B. Obtain a tympanogram reading prior to initiating the test. C. Place a vibrating tuning fork on the top of the child's head. D. Hold a vibrating tuning fork 1 to 2 cm (0.4 to 0.8 in) from the child's ears.

Correct Answer is C

Explanation

Choice A rationale:

Measuring the amount of time the child can hear the sound is not the correct action when performing Weber's test. Weber's test is used to assess hearing acuity and lateralization. In this test, a vibrating tuning fork is placed in the middle of the patient's forehead, and the patient is asked if the sound is heard equally in both ears or if it is louder in one ear. This helps identify whether there is a conductive or sensorineural hearing loss. The duration of hearing the sound is not relevant to this test.

Choice B rationale:

Obtaining a tympanogram reading is not necessary before initiating Weber's test. Tympanometry assesses the movement of the eardrum in response to changes in air pressure and can help diagnose conditions like middle ear effusion or eustachian tube dysfunction. However, Weber's test focuses on lateralization of sound and does not require tympanogram readings.

Choice C rationale:

Placing a vibrating tuning fork on the top of the child's head is the correct action for performing Weber's test. By doing so, the nurse can assess whether the sound is perceived equally in both ears or if it is lateralized to one ear. If the sound is lateralized, it can provide valuable information about the type of hearing loss the child may have, whether it's conductive or sensorineural.

Choice D rationale:

Holding a vibrating tuning fork 1 to 2 cm (0.4 to 0.8 in) from the child's ears is not the correct technique for Weber's test. Placing the tuning fork directly on the patient's forehead is essential for accurate assessment. Holding it close to the ears can lead to misinterpretation of the test results.
