A nurse in the emergency department is assessing a preschooler who has a facial laceration. The nurse should identify which of the following findings as a potential indication of child sexual abuse?

The child exhibits discomfort while walking

The child has thin extremities

The child has bruises on the upper back

The child is wearing a stained shirt

Answer and Explanation

The Correct Answer is A

A - This is correct because discomfort while walking can indicate genital trauma or infection, which are possible signs of sexual abuse.

B - This is incorrect because thin extremities can be caused by many factors, such as malnutrition, genetic disorders, or chronic diseases, that are not necessarily related to sexual abuse.

C - This is incorrect because bruises on the upper back can result from accidental injuries, such as falls or bumps, or from physical abuse, such as hitting or kicking, but not specifically from sexual abuse.

D - This is incorrect because a stained shirt can be due to poor hygiene, food spills, or environmental factors, but not necessarily from sexual abuse.

Correct Answer is A

Explanation

a. Improves muscle strength.

Explanation:

Neostigmine is a medication used in the treatment of myasthenia gravis (MG). It belongs to a class of drugs called cholinesterase inhibitors. Neostigmine works by inhibiting the breakdown of acetylcholine, a neurotransmiter involved in muscle contraction. In MG, there is a decrease in the amount of acetylcholine available at the neuromuscular junction, leading to muscle weakness and fatigue.

By inhibiting the breakdown of acetylcholine, neostigmine helps to increase the concentration of acetylcholine at the neuromuscular junction. This, in turn, improves muscle strength and can alleviate the symptoms of weakness and fatigue associated with MG.

Option b, destroying the antibodies that cause MG, is not accurate. Myasthenia gravis is an autoimmune disorder characterized by the presence of antibodies that interfere with neuromuscular transmission.

Neostigmine does not directly target or eliminate these antibodies.

Option c, enhancing immune system function, is not accurate either. Neostigmine primarily acts on the neuromuscular junction to improve muscle strength and does not have a direct eﬀect on immune system function.

Option d, preventing excessive coughing, is not the primary action of neostigmine. While increased muscle strength may indirectly improve respiratory function and reduce coughing in individuals with myasthenia gravis, it is not the primary indication or action of neostigmine.

Therefore, the most accurate information to include in teaching about neostigmine for a client with myasthenia gravis is that it improves muscle strength.

A. Hypoxemia B. Tension pneumothorax. C. Malignant hypertension D. Atelectasis

Correct Answer is B

Explanation

A. Hypoxemia is a condition of low oxygen levels in the blood. PEEP can actually improve oxygenation by preventing alveolar collapse and increasing functional residual capacity.

B. Tension pneumothorax is a life-threatening condition of air accumulation in the pleural space that causes increased intrathoracic pressure and compresses the lungs, heart, and great vessels. PEEP can increase the risk of tension pneumothorax by creating excessive positive pressure in the airways and alveoli.

C. Malignant hypertension is a severe form of high blood pressure that can cause organ damage and stroke. PEEP can cause a transient increase in blood pressure due to increased intrathoracic pressure, but it does not cause malignant hypertension.

D. Atelectasis is a condition of partial or complete lung collapse due to alveolar collapse or obstruction. PEEP can prevent or treat atelectasis by maintaining positive pressure in the airways and alveoli.
