A nurse is reviewing the medical record of a client.
The client is an 18-year-old admitted to an inpatient psychiatric unit after passing out at home. The client reports using laxatives and "making myself throw up after eating" for about 6 months.
After reviewing the client's medical record and new diagnostic results, the nurse determines the client is at risk for further health issues.
The client is at risk for developing which of the following?

Hypomagnesemia

Renal failure

Heart failure

Hyperthyroidism.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

The client’s reported behavior of using laxatives and inducing vomiting after eating can lead to a condition known as hypomagnesemia. Hypomagnesemia is a condition characterized by low levels of magnesium in the blood. This condition can be caused by poor intake, excessive loss, or movement of magnesium from the blood into less accessible locations. The use of laxatives can lead to excessive loss of magnesium through increased bowel movements. Similarly, self-induced vomiting can also result in a loss of magnesium. Therefore, the client’s behavior puts them at risk for developing hypomagnesemia.

Choice B rationale:

Renal failure, also known as kidney failure, occurs when the kidneys lose their ability to filter waste products from the blood. While the use of laxatives and self-induced vomiting can lead to dehydration, which can strain the kidneys, these behaviors are not directly associated with renal failure. Therefore, while it’s possible for the client to develop kidney problems, it’s less likely compared to hypomagnesemia.

Choice C rationale:

Heart failure occurs when the heart muscle doesn’t pump blood as well as it should. This condition can cause symptoms like shortness of breath, swelling, fatigue, and other symptoms. While severe electrolyte imbalances, such as those that might result from the use of laxatives and self-induced vomiting, can affect heart function, they would typically result in arrhythmias (irregular heartbeats) rather than heart failure. Therefore, it’s less likely for the client to develop heart failure based on the behaviors described.

Choice D rationale:

Hyperthyroidism is a condition where the thyroid gland produces and releases too much thyroid hormone. This condition can cause symptoms like rapid heartbeat, weight loss, and anxiety. The client’s behaviors of using laxatives and inducing vomiting after eating do not directly influence the production of thyroid hormones. Therefore, it’s less likely for the client to develop hyperthyroidism based on the behaviors described.

Correct Answer is D

Explanation

Choice A: Limit the amount of time available to interact with others

While the client's behavior may indirectly limit their interactions with others by occupying their time, this is not the primary function of their actions. The core motivation lies in reducing anxiety, not social avoidance.

Choice B: Manipulate and control others' behaviors

Although the client's cleaning may influence others to tidy up, this is not a deliberate attempt to control their behavior. The primary drive stems from the client's internal need for order and cleanliness, not a desire to dictate the actions of others.

Choice C: Focus attention on meaningful tasks

While the act of cleaning can be productive and contribute to a pleasant environment, it's not the primary function or intention behind the client's behavior. Their actions are primarily driven by the need to quell anxiety, not necessarily to accomplish meaningful tasks.

Choice D: Decrease anxiety to a tolerable level

This is the most accurate rationale for the client's behavior. Individuals with OCD engage in compulsions, like excessive cleaning, to alleviate the intense anxiety associated with their intrusive thoughts and obsessions. In this case, the act of picking up after others provides the client with a sense of order and control, thereby reducing their anxiety to a manageable level.

Elaboration:

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by intrusive thoughts (obsessions) and repetitive behaviors (compulsions). Individuals with OCD experience significant anxiety due to their obsessions and feel compelled to engage in compulsions to manage that anxiety.

In the scenario presented, the client's constant cleaning behavior likely stems from an obsession with order and cleanliness. This obsession triggers anxiety when the environment is perceived as messy or disorderly. The act of picking up after others serves as a compulsion, a ritualistic behavior performed to reduce the anxiety caused by the obsession. By restoring order and cleanliness, the client temporarily alleviates their anxiety and achieves a sense of control over their environment.

It's important to recognize that the client's cleaning behavior, while seemingly productive, is primarily driven by their internal need to manage anxiety, not by a genuine desire to help others or maintain a tidy environment. This understanding is crucial for the nurse to effectively support the client and guide them towards healthier coping mechanisms for managing their OCD symptoms.

Correct Answer is ["2"]

Explanation

Step 1: Identify the required dose of lithium, which is 300 mg.

Step 2: Identify the available dose of lithium carbonate, which is 150 mg per capsule.

Step 3: Calculate the number of capsules needed using the formula: Number of capsules = Required dose ÷ Available dose.

Numberofcapsules=300 mg150 mg/capsule

$Number\ of\ capsules = {300\ mg \over 150\ mg/capsule}$

Step 4: Solve the equation.

Numberofcapsules=2 capsulesNumberofcapsules=2capsules

So, the nurse should administer 2 capsules per dose to achieve the required lithium dose of 300 mg.
